Frequently Asked Questions
What voltage is this motor rated for?
This motor is rated for 60-96V operation. Please confirm your battery pack voltage matches before ordering.
What is the rated and peak power of this motor?
The rated power is 4000-8000W, and peak power reaches 6000-15000W for short-duration high-load operation.
What are the speed and torque ratings?
Rated speed is 4800rpm; peak torque is 50-60N.m. Actual performance depends on the controller settings and the load.
What is the protection level of this motor?
The motor is rated IP67, so it is protected against dust and water ingress to that level when the housing and connectors are properly sealed.
Which position sensor does this motor use?
It uses a MAGNETIC ENCODER position sensor, providing accurate rotor position feedback for smooth and efficient operation.
Can the specification be changed for bulk orders?
This model is supplied as a standard catalog product with fixed specifications – the motor itself cannot be modified. If you need a different voltage or power rating, we can recommend an alternative model from the same series. Please send us your target specification and we will advise the closest option.
