IEC mounting and replacement
IEC metric motors in this range use standardized shaft center height (H) and foot-mounting hole spacing so a same-frame replacement typically bolts to the existing base without machining. Confirm H, B, shaft diameter, and flange code on the nameplate and datasheet (IEC 60072-1) before ordering. Do not use this page as a millimetre drawing.
Typical construction is totally enclosed fan-cooled (TEFC, IC411) with IP55 protection: dust-tight enclosure and protection against water jets.
Before you order
- kW and poles vs the installed motor nameplate
- Foot vs flange code (B3 / B5 / B35)
- Voltage and frequency (220–690 V class as specified)
- Duty S1 vs inverter supply (consider YVF2)
Same frame, other efficiency classes
JW general-purpose series use a Class F insulation system designed around Class B temperature rise, giving thermal margin in industrial ambients.
FAQ
What is the average braking time for YEJ series motors?
The braking time of YEJ series motors is exceptionally fast, typically ranging from 0.15 to 0.45 seconds depending on the frame size. This makes them ideal for equipment requiring precise positioning or emergency stops, such as elevators and packaging machinery.
Can the YEJ motor be released manually during a power failure?
Yes. Our YEJ motors come equipped with a manual release handle. This allows you to manually release the brake and rotate the shaft in case of a power outage or during machine maintenance, ensuring operational flexibility and safety.
How do I adjust the braking torque of a YEJ motor?
The braking torque can be adjusted by tightening or loosening the pressure springs inside the brake assembly. For optimal performance, we recommend maintaining the air gap between 0.2mm and 0.5mm to ensure consistent friction and rapid response.
Can I replace another IEC frame 160 motor with YEJ Brake Motors?
If the installed motor is a standard IEC metric frame 160 with the same mounting and shaft, YEJ Brake Motors is designed as a dimensional replacement. Always match kW, poles, voltage, and duty.
