Electric Motor Servo
Understanding Electric Motor Servos and Alternatives from JWMotor
Electric Motor Servo is a job on an industrial machine: lock kW (or hp at 0.746), poles so speed stays the same, 50 or 60 Hz, and whether a VFD sits on the motor. JWMotor quotes IEC three-phase TEFC motors for that job — YE3 (IE3) for general S1, Y2 when the spare must stay IE2, YVF2 on inverter supply.
Brake, gear and special shafts are YEJ, R/F/K/S or a custom winding. Send voltage, frequency, kW or hp, poles, mounting and a nameplate photo to contact JWMotor.
How we quote Electric Motor Servo
Terms
- Duty vs model
The search names a job. The JW nameplate names kW, poles, IE class and frame. We map the job onto YE3, Y2 or YVF2 from those numbers.
- IE class
IE2/IE3/IE4 is IEC 60034-30-1. YE3 is JW’s usual IE3 motor; Y2 is IE2; YE4 is IE4.
- Custom
Missing leaflet row, odd voltage or shaft is still an enquiry. We quote a winding around your plate.
FAQ
Which JW motor should I enquire for Electric Motor Servo?
Start with YE3 (IE3) for general S1 three-phase. Stay on Y2 if the spare must remain IE2. Use YVF2 on a VFD, YEJ with a brake, and R/F/K/S if the plate is a helical gearmotor.
What do I send for a quote?
Voltage and frequency, kW or hp, poles or r/min, foot or flange, IE class if printed, and a nameplate photo.
Can you customise if this is not a stock leaflet row?
Yes. Unusual voltage, flange, shaft or winding is a normal JW quote. Send the plate — we design around it rather than stopping at the catalogue.
Is this a drop-in for another brand?
When H, shaft, mounting, kW and poles match. The logo on the old plate does not pick the JW series by itself.
Stock or custom
If this is not a JW stock leaflet motor, we still quote custom windings, voltages, mountings and special duty. Write voltage and frequency (and whether the supply is single-phase or three-phase), kW or hp, speed or poles, foot or flange, and attach a nameplate photo.
