Are electric motors used in electric cars alternating current or direct current?Does the 48V battery output direct current or alternating current? Does the DC converter convert AC to direct current?
Most electric cars are powered by Holzer motors, which are brushed and brushed. Similar to AC and DC, it controls the rotation of the battery DC into AC pulses by the controller. The pulse signal is similar to the AC, and each pulse rotates one step.
Transfer Hall signal to the controller, the controller through the thick line (not hall line) to the power supply, motor coil motor rotation, magnet and coil (precisely winding on the stator coil, in fact, the hall is usually installed in the stator) to rotate, Hall position signal induces a new, thick line the controller to change the direction of the current power supply to the motor coil, the motor continues to rotate (coil and magnet coil position changes, must change the direction of the current, the corresponding motor can continue to move in one direction or the motor will be in a position to swing around, rather than continuous rotation), this is the electronic commutation.
Working principle of Holzer motor:The signal line hall transfer motor inside the magnet relative to the coil position, according to the signal controller three hall can know at this time should be how to supply power to the coil motor (current Hall signal, the motor coil for different should give corresponding direction), that is the hall of state is not the same as the direction of current coil is not the same.
