Mounting and duty
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.
Most general-purpose TEFC machines in the catalog are intended for continuous duty (S1) on pumps, fans, compressors, and conveyors. Short-time or intermittent duty, frequent starts, or inverter supply may need a different series (for example YVF2 for VFD or YEJ for brake). Match enclosure (typically IP55 / IC411 TEFC) to dust, moisture, and washdown at the site.
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.
Is YEJ Brake Motors a drop-in for another IEC IEC motor?
Often the feet and shaft height follow IEC 60072-1, but you still match kW, poles, shaft diameter, voltage, and mounting code from the nameplate—not from the series name alone.
