The nameplate of the failed motor is worn off; the only thing still legible on the side of the housing is "132M". If that is the most reliable piece of information you have, searching for a replacement by frame number is faster than searching by power. This article arranges the price list by IEC frame size rather than by kW: for every step from frame 63 to frame 355 it shows which model is in the shop, its price excluding and including VAT, and how to identify a motor with the same dimensions as the old one.
A Frame Number Is Really a Measurement: Shaft Height
Under IEC 60072, the frame number gives the distance in millimetres from the surface on which the feet sit to the centre of the shaft. A frame 132 motor has its shaft centre 132 mm above the base; in frame 160 this distance is 160 mm. In dimension tables this value is the letter "H".
In practice: two standard motors with the same frame number are designed to the same shaft height and foot layout, even if they come from different suppliers. The axis of a coupled pump or gearbox stays where it is; no shims under the feet and no re-welding of the base. That is why two quotes for the same frame are also equivalent in installation labour.
Decoding the Model Code: DRG-132M-4
Model codes in the DRG Motor shop carry the frame information directly. The code DRG-132M-4 splits into three parts:
- 132 — frame number, i.e. 132 mm shaft height.
- M — frame length. S is short, M medium, L long. When the letter changes, the axial distance between foot holes ("B" in the catalogue) changes; the shaft height does not.
- 4 — number of poles. 2 poles means about 3000 rpm, 4 poles 1500 rpm, 6 poles 1000 rpm.
Some codes add a digit after the letter, such as DRG-132S1-2 and DRG-132S2-2. The suffix separates two power options within the same frame and length letter; the external mounting dimensions are shared. Small frames use only a sequence digit instead of a length letter: DRG-801-4 and DRG-802-4 are the first and second power options of frame 80, while DRG-632-2 is the 2-pole model in frame 63.
Price Table by Frame Size: From 63 to 355
For each frame size we took the cast iron 1500 rpm model in the shop. Cast iron 1500 rpm options start at frame 80, so for rows 63 and 71 we listed the aluminium model; in frame 63 the shop only has a 3000 rpm model. Where a frame has more than one 1500 rpm model (e.g. 315L) we show the first power step.

Note that as the frame number grows, the price rises in steps rather than along a smooth curve. The sharpest jump is between 250M and 280S: from 93,247.00 TRY to 131,670.00 TRY excl. VAT. The bearing table in the catalogue helps explain this transition: the 4-pole frame 250 uses a 6314-C3 bearing, frame 280 a 6317-C3, so the mechanical design moves up a class.
Same Frame, Different Poles: Comparing 132S and 160M
A frame number alone does not tell you the power. Frame 132S takes 3 kW at 6 poles, 5.5 kW at 4 poles and 7.5 kW at 2 poles. The reason is torque: as speed drops, the torque needed for the same power grows, and torque is what really sets the housing volume.
| Frame | Model (cast iron) | Poles / speed | Power | Torque (Nm) | Excl. VAT | Incl. VAT (20%) |
|---|---|---|---|---|---|---|
| 132S | DRG-132S-6 | 6 / 1000 rpm | 3 kW | 29.6 | 13,343.00 TRY | 16,011.60 TRY |
| 132S | DRG-132S-4 | 4 / 1500 rpm | 5.5 kW | 36 | 15,438.50 TRY | 18,526.20 TRY |
| 132S | DRG-132S1-2 | 2 / 3000 rpm | 5.5 kW | 17.9 | 15,290.00 TRY | 18,348.00 TRY |

Two conclusions follow. First, power within one frame can vary by more than a factor of two, but the price does not rise in the same ratio; in 132S the gap between the 3 kW 6-pole model and the 7.5 kW 2-pole model is about 25 percent. Casting, bearings and fan depend on the frame, not on the power. Second, if your old motor is a 132S 3 kW 6-pole unit, the 2-pole model in the same frame will physically fit the base but will triple the speed of your machine. A frame match only makes sense together with a pole match.
Finding the Same Frame as the Old Motor: Measuring on Site
If the nameplate cannot be read, work in this order:
- Check the frame field on the nameplate. If it shows something like "132M" or "160L", use it directly; you do not need the other nameplate fields at this stage.
- Measure the shaft height. Measure from the underside of the foot to the top of the shaft and subtract half the shaft diameter. If the result is 132 mm, the frame is 132.
- Measure the foot hole spacing in both directions. The centre-to-centre distance across the shaft is A, along the shaft is B. The B dimension determines the letter S, M or L.
- Measure the shaft diameter (D) and shaft extension length (E). The coupling or pulley bore was machined to these.
- If there is a flange, note the flange outer diameter and the pitch circle diameter of the bolt holes.
- Match against the catalogue dimension table: if H, A, B and D fall on the same row, the frame is confirmed.
In frames 225 and above, the shaft diameter of 2-pole models can differ from 4 and 6-pole models; check the coupling bore separately against the D dimension.
Decision Table for Frame Matching
| Situation on site | What to do |
|---|---|
| Frame, poles and power are the same as the old motor | Choose the row with the same code in the shop; mounting dimensions match exactly. |
| Old motor is the same frame but kept tripping the thermal overload | Look at the 1 and 2 suffix codes of the same frame (e.g. 132S1/132S2); the next power up may fit without changing dimensions. |
| Old motor is aluminium, cast iron is being considered | Shaft height and foot layout are the same; only the weight increases, so plan lifting and handling accordingly. |
| Frame cannot be measured, only kW and speed are known | Find the shop row by power and speed, then confirm the frame from the table above. |
| Dimensions do not fit any standard row | The motor may be a special build; contact us with photos of the measurements and we will identify the equivalent frame together. |
Frame Details to Put in the Order Note
- Frame code and length letter (e.g. 160M), number of poles and power.
- Mounting type: shop list prices are for the standard foot-mounted model; state it in the note if you need a flange version.
- Cable entry: the catalogue gives 2 × M32×1.5 gland entries for frames H112–132 and 2 × M40×1.5 for H160–180; prepare your existing cable gland accordingly.
- Delivery address and shipping preference (delivery and shipping).
Frequently Asked Questions
Why can two motors with the same frame number have different prices?
The same frame comes in different pole counts and power options, and the housing material (aluminium or cast iron) also changes the price. Compare with these three held constant.
Is a 355 kW motor in frame 355?
Not in the shop list. At 1500 rpm the 355 kW model is DRG-400M-4, and its frame is 400M. The first number in the code always refers to the frame; power is a separate field.
Is there a cast iron option in frame 71?
In the shop list, the only cast iron model in frame 71 is the 3000 rpm 0.55 kW DRG-712-2; the 1500 rpm models in this frame are aluminium.
I don't know the frame, only what the machine needs. Where should I start?
First find the required power; the electric motor calculators help with this step for pumps, fans and conveyors. Once power and speed are known, read the frame from the tables above.
