The speed of the motor is slow and the mileage is shortened
There's really no need to change the controller. Besides, we can't find the manufacturer's controller performance test report and have no right to speak.
1. is the rear wheel soft and noisy?.2. see if the motor's magnetic disk is displaced.The motor is small rare earth motor United 36V500W is only the rotor? Of course, it is possible to open carefully observed, there are problems that can be found, pay special attention to bearing diameter is loose, wear, add shaft can be.
Hello Careful, rigorous, and a real expert. Electric control after the water can run for several days, why change, can run, there should be no big impact. In this case, the motor is obviously more hot than before, and the mileage is obviously shortened. I think it's caused by mechanical trouble. Please check your motor carefully.
Oh, the power of 36v500w's point machine is not small. You are so confident. You can only turn on the rotor without any mechanical trouble. Motor winding will not have short-circuit fault, can only see the winding insulation resistance, with shake table check, must pay attention to disconnect the motor all links, heat is not Holzer, it is easy to breakdown. The rotor has no professional tools and cannot detect the size of the magnetic force. It can only be done by experience. Good luck
