Every product page in the DRG shop is organised in three tables: basic nameplate data, 50 Hz electrical performance, and mechanical data with B3 mounting dimensions. Below them, a short description of the motor and the other speed options at the same power are listed.
Top table: the nameplate equivalent
Power in kW and HP, synchronous speed and number of poles, frame material with IEC frame and shaft height, winding voltage (e.g. 400/690 V Δ/Y) and protection/insulation class (IP55, F) appear here. This table also states that shipping is not included in the price.
Electrical performance table
- Rated speed at full load (lower than the synchronous speed by the slip)
- Power factor cos φ
- Rated current at 380, 400 and 415 V
- Rated torque at the shaft
- Starting and breakdown torque ratios, and the starting current ratio
These values serve as inputs for selecting cables, switchgear and protection; selection and setting depend on the assessment of qualified electrical personnel.
Mechanical data and dimensions
The drive-end bearing type, cable entry, cooling method (IC 411), winding and shaft material, possible mounting types (B3, B5, B14, B35) and rotor balance class are listed. The ambient temperature and altitude limits and the paint colour are also in this section. The dimensions part covers foot hole spacing A×B, shaft diameter and length D×E, the distance C from the shaft shoulder to the foot hole, key width, foot hole diameter, overall length and frame diameter.
For flange mounting
The dimensions on the page are for foot-mounted B3; B5 or B35 flange dimensions are given in the DRG technical drawings.
From the page to the order
The product page has links to the payment options, return and delivery policies, plus a WhatsApp button for asking questions about the motor. For an example, open the page of the 4 kW 1500 rpm DRG-112M-4 cast iron model, and move on to other models via the shop listing all models.
