bldc motor winding open circuit causes and treatment

Posted by on January 14, 2022 Comments Off on bldc motor winding open circuit causes and treatment

bldc motor winding open circuit the motor does not start, three-phase current imbalance, abnormal noise or vibration, temperature exceed the allowable value or smoke.

Winding open circuit due to poor welding or the use of corrosive fluxes, welding and then not cleaned, it may cause solder pot or loose; by mechanical stress or collision coil short-circuit, short circuit and ground fault also can lead burning, and burning in of a few wires in a short circuit or a few wires, the other a few wires as current as temperature rises, causing fever and winding circuit. Generally divided into disconnected end of one phase winding, inter-turn short circuit, parallel circuit branch office, multi-wire and burned in an open circuit, broken rotor cage.

hub motor short circuit causes:
1, when in the repair and maintenance problems touched off or manufacturing quality.
2, the winding of the components, pole (phase) winding and the lead group and the first welding wire and other wire bad, long-running hot sealing off.
3, by mechanical force and electromagnetic force or pull off the winding damage.
4, short circuit and the ground turns white sometimes cause severe burning or winding fuse and so on.

hub motor short-circuit approach:
1, open circuit at the end, the connection is completed weld, wrapped in insulating material, put pipe insulation, banding is good, and then dried.
2, as inter-turn winding, white short-circuit and ground and other reasons caused serious burnt windings should generally be replaced with new winding.
3, the open circuit point in the tank, is a small break to do emergency treatment, the use of groups out method to identify breakpoints and the Ministry of winding down its connected and insulated qualified to use. If your business is a buy and sell or something, you might need motors can be risky and dangerous.
4, the cage can be broken rotor cage welding, cold-connection of a repair or exchange.

Why hub motor out of step?

Posted by on January 14, 2022 Comments Off on Why hub motor out of step?

1, hub motor rotor of the stepper motor acceleration is slower than the rotating magnetic field, that is lower than the phase velocity change arising. This is because the lack of input electrical power, generated in the stepper motor torque can not make synchronous rotor speed to follow the stator magnetic field rotation rate, causing loss of step. And any high frequency than when the frequency is bound to work out of step. This illustrates the step-step motor drag is not enough. Once the reduced load, or increase the winding excitation current, it is possible to overcome the loss of step.

2, hub motor rotor speed is higher than the average of the average rotation speed of the stator magnetic field. Then the stator excitation power for longer periods, than the time required for the rotor step further, the rotor step process to get too much energy, resulting in pediment and the backlash of the swing oscillations. When severe enough to cause oscillation of step.
