To describe a motor fully over the phone, read out the nameplate values together with their units, then explain the fixing method, shaft diameter, shaft height and what the machine does. Giving figures without units is the most frequent cause of misunderstandings during a call.
Notes to prepare before the call
| Heading | What to say |
|---|---|
| Power | Stating whether it is kW or HP |
| Speed | The rpm value on the nameplate, e.g. 1475 |
| Voltage and frequency | The two voltage values on the nameplate and the Hz |
| Fixing method | Foot-mounted, flange-mounted or both |
| Shaft | Diameter and protruding length, in mm |
| Shaft height | From the foot face resting on the floor to the middle of the shaft, in mm |
| Application | Pump, fan, crusher, conveyor and so on |
Expressions that get misunderstood
- “A 380 motor” describes the voltage but does not show the winding type; read both voltage values on the nameplate together.
- “1400 rpm” points to a 4-pole motor and “2800 rpm” to a 2-pole one; give the number without rounding it.
- Descriptions such as “large size” or “medium size” are no substitute for the frame number.
- For frame codes with letters, spell out S, M and L separately; 132S and 132M are different lengths.
Back up the call with photos
If the nameplate is legible, sending a photo of it via the WhatsApp line in addition to reading it aloud reduces errors. Being next to the motor during the call, with a tape measure in hand, means follow-up questions can be answered on the spot.
You can reach DRG on +90 (542) 666 11 11 or +90 (533) 777 04 44. Looking at the three-phase motor list in the shop before the call helps you see in advance the models close to the values you are describing.
