IEC 200L Frame Motors: Models & Dimensions

DRG Motor offers five cast iron three-phase motors in the IEC 200L frame: 18.5 and 22 kW at 6 poles (200L1-6, 200L2-6), a single 30 kW model at 4 poles (200L-4), and 30 and 37 kW at 2 poles (200L1-2, 200L2-2). All share a 200 mm shaft height, a 55 × 110 mm shaft and 318 × 305 mm foot hole spacing; the B5 flange is 400 mm outside, with a 300 mm spigot and a 350 mm bolt circle.

Grey DRG three-phase asynchronous electric motor – 200L frame models and dimensions

You can filter every model by power and speed in the DRG online motor shop, and see the other cast iron IEC motors on the three-phase asynchronous electric motors page. Below we go through the dimensions that matter when choosing a 200L and the pitfalls specific to this frame.

Which DRG motors are built on the 200L frame?

In the DRG range, 200L is the centre of the 30 kW class. One frame cross-section carries five power ratings across three pole numbers. All models are wound for 400/690 V (Δ/Y), so they run in delta on a 400 V supply and suit star-delta starting. Bearings are 6312-C3; cable entry is 2 × M50×1.5.

Model	Power	Speed class → rated speed	Poles
DRG-200L1-6	18.5 kW (25 HP)	1000 rpm → 980 rpm	6-pole
DRG-200L2-6	22 kW (30 HP)	1000 rpm → 980 rpm	6-pole
DRG-200L-4	30 kW (40 HP)	1500 rpm → 1475 rpm	4-pole
DRG-200L1-2	30 kW (40 HP)	3000 rpm → 2960 rpm	2-pole
DRG-200L2-2	37 kW (50 HP)	3000 rpm → 2960 rpm	2-pole

"1000 / 1500 / 3000 rpm" is the synchronous speed class; the rated speed on the nameplate is slightly lower because of slip. Use the nameplate speed, not the class, when sizing pulleys or a gearbox output: 980 rpm at 6 poles, 1475 rpm at 4 poles, 2960 rpm at 2 poles.

200L1, 200L2 and plain 200L: what the suffix tells you

In DRG type codes, the 1 or 2 after the frame separates two power steps that fit the same frame at the same pole number. At 6 poles, 200L1 = 18.5 kW and 200L2 = 22 kW; at 2 poles, 200L1 = 30 kW and 200L2 = 37 kW. At 4 poles there is only one rating in this frame (30 kW), so the code is simply 200L-4.

In DRG data, the B3 dimensions (H, A, B, C, K, L) and the shaft are the same for all five models; what differs is rated power, current and torque. So the way to tell a 200L1 from a 200L2 is the kW on the nameplate, not a measurement. When replacing an old motor, do not rely on "200L" alone; read the pole number and kW together.

Same 30 kW, two different motors: 2-pole vs 4-pole

The most common mix-up on 200L is that 30 kW appears twice: DRG-200L1-2 (3000 rpm class) and DRG-200L-4 (1500 rpm class). Same power, same shaft, same flange — yet the torque delivered at the shaft is almost double. Torque follows M = 9550 · P / n:

DRG-200L1-2: 9550 · 30 / 2960 ≈ 96.8 Nm
DRG-200L-4: 9550 · 30 / 1475 ≈ 194.2 Nm

High-speed loads such as fans, centrifugal pumps and compressors usually take 2 poles; conveyors, mixers, crushers and gearbox inputs mostly take 4 poles. The 6-pole 200L1-6 and 200L2-6 serve low-speed, high-torque duty: the 22 kW 200L2-6 gives 214.4 Nm, more rated torque than the 30 kW 4-pole model.

Model	Rated current at 400 V	Rated torque	Shaft (D × E)
DRG-200L1-6	35.9 A	180.3 Nm	55 × 110 mm
DRG-200L2-6	42.5 A	214.4 Nm	55 × 110 mm
DRG-200L-4	53.8 A	194.2 Nm	55 × 110 mm
DRG-200L1-2	52.1 A	96.8 Nm	55 × 110 mm
DRG-200L2-2	64 A	119.4 Nm	55 × 110 mm

200L B3 foot-mounted dimensions

For foot (B3) mounting, base holes and shaft height decide the fit. The values below come from the DRG catalogue and are identical for all five models.

Dimension	Meaning	Value
H	Shaft centre height (from floor)	200 mm
A	Foot hole spacing (across)	318 mm
B	Foot hole spacing (lengthwise)	305 mm
C	Shaft shoulder to nearest foot hole	133 mm
K	Foot holes	4 × Ø18.5 mm
D × E	Shaft diameter × length	55 × 110 mm
F	Key width	16 mm
AC / AD	Frame diameter / axis to top of terminal box	397 / 299 mm
L	Overall length	779 mm

When replacing a motor on a coupled machine, compare H = 200 mm and the C = 133 mm shoulder-to-foot-hole distance; if C differs, the coupling gap changes. Drawings are on the 2D technical drawings and 3D models pages.

200L B5 flange dimensions: P, N, M and S separately

When ordering a flange (B5) motor, four values must not be confused: outer diameter P, spigot diameter N, bolt circle M and hole diameter S. The DRG catalogue lists a single B5 row for 200L, valid for 2, 4, 6 and 8 poles.

Dimension	Meaning	Value
P	Flange outer diameter	400 mm
N	Spigot (pilot) diameter	300 mm
M	Bolt circle diameter	350 mm
S	Flange hole diameter	18.5 mm
T	Spigot depth	5 mm
LA	Flange thickness	17 mm
G / DH	Key seat dimension / shaft end thread	49 mm / M20×42
L / LB	Overall length / flange face to rear end	779 / 669 mm

This sets 200L apart from its neighbours. On 225M the B5 table has two rows: a 55 × 110 mm shaft at 2 poles and 60 × 140 mm at 4/6/8 poles. On 200L the shaft is 55 × 110 mm at every pole number. B5 values for all frames are collected in the B5 motor flange dimensions table, and shaft sizes by power in the motor shaft diameter by kW table.

Comparison with neighbouring frames: same power, another frame

The same kW is not always in the same frame. Here are the other cast iron DRG equivalents of the 200L ratings; note how the shaft size changes.

Power	200L model	DRG model in another frame
18.5 kW	DRG-200L1-6 (6-p, 55 × 110 mm)	DRG-160L-2 – 160L, 2-p, 42 × 110 mm DRG-180M-4 – 180M, 4-p, 48 × 110 mm
22 kW	DRG-200L2-6 (6-p, 55 × 110 mm)	DRG-180M-2 – 180M, 2-p, 48 × 110 mm DRG-180L-4 – 180L, 4-p, 48 × 110 mm
30 kW	DRG-200L-4 (4-p, 55 × 110 mm) DRG-200L1-2 (2-p, 55 × 110 mm)	DRG-225M-6 – 225M, 6-p, 60 × 140 mm
37 kW	DRG-200L2-2 (2-p, 55 × 110 mm)	DRG-225S-4 – 225S, 4-p, 60 × 140 mm DRG-250M-6 – 250M, 6-p, 65 × 140 mm

The flange table changes too:

Frame	Poles	P / N / M	Shaft D × E
180M	2, 4, 8	350 / 250 / 300 mm	48 × 110 mm
180L	4, 6, 8	350 / 250 / 300 mm	48 × 110 mm
200L	2, 4, 6, 8	400 / 300 / 350 mm	55 × 110 mm
225S	4, 8	450 / 350 / 400 mm	60 × 140 mm
225M	2	450 / 350 / 400 mm	55 × 110 mm
225M	4, 6, 8	450 / 350 / 400 mm	60 × 140 mm

In practice, anyone moving from a 180 frame to 200L on the same machine has to allow for a larger flange (P 350 → 400 mm) and a larger shaft (48 → 55 mm). The flange side of the 180 and 200L options is covered separately in the 22 kW flange motor and 18.5 kW flange motor articles.

B14, B34 and gearbox input: what needs confirming?

For 200L the DRG catalogue contains only the large B5 flange table; there is no B14 small-flange table in the catalogue, so we do not quote B14 dimensions for this frame. If you need a B14 or B34 connection, send the flange outer diameter, bolt circle, spigot diameter and thread size on WhatsApp and we will confirm. Foot and flange variants are compared in the motor mounting types article.

For a 200L motor going onto a gearbox, the size code alone is not enough. Read these from the gearbox input nameplate or drawing and compare them with the DRG data above: P / N / M / S of the input flange, input bore diameter (motor shaft 55 mm), key width (16 mm), ratio and permitted input power/torque. The relation between gearbox size and motor frame varies by manufacturer, so compare dimensions rather than relying on a fixed matching table. More detail is in choosing a flange motor for a gearbox. DRG Motor is an electric motor manufacturer, supplier and seller; it does not sell gearboxes, only the motor.

Pre-order checklist

Power and poles: if you need 30 kW, decide between 2 poles (DRG-200L1-2) and 4 poles (DRG-200L-4).
Mounting: B3, B5 or B35. With B35 both the feet (A 318 × B 305 mm) and the flange (P 400 / M 350 mm) must match. Ordering steps are in the B3, B5 and B35 ordering guide.
Shaft: 55 × 110 mm, key 16 mm, shaft end thread M20×42. Check against the coupling or pulley bore.
Electrical: 400/690 V (Δ/Y); current between 35.9 and 64 A depending on model.
Space: overall length L 779 mm and terminal box height (HD 499 mm, B5) can matter in tight spaces.

Ordering by frame size is explained in the shaft and frame size order guide, and all dimensions are in the DRG technical and product catalogue. Send a photo of your motor nameplate and the shaft/flange size, and we will identify the right 200L model with you.

Frequently asked questions

What is the shaft diameter of a 200L motor?

All DRG 200L models have a 55 mm shaft, 110 mm long, with a 16 mm key. There is no shaft difference between 2 and 4 poles; in the DRG range that difference starts at 225M.

200L1-2 and 200L-4 have the same power; are they interchangeable?

Mounting dimensions match, but no: one runs at 2960 rpm, the other at 1475 rpm, with 96.8 Nm versus 194.2 Nm of torque. Change the speed and the pump, fan or gearbox output changes too.

Is a 200L motor available with an aluminium frame?

No. DRG's aluminium range covers 0.25–11 kW; the five 200L models have cast iron frames.

Is the 200L B5 flange the same as the 180 frame flange?

No. 180M/180L has P / N / M = 350 / 250 / 300 mm, 200L has 400 / 300 / 350 mm. To compare frames side by side, see the electric motor price list by frame size.
