The brush motor adopts the carbon brush as the two contacts of the motor power supply, and is controlled by the speed control switch and the controller, and the stepless speed regulation of the electric bicycle of 0-20 km/hour is achieved through the secondary deceleration of the gear and the overrunning clutch.
The brushed high-speed motor currently used has high gold content, strong motor reduction gear strength, good wear resistance, and reasonable design, so the repair rate is low; and the cost of maintenance and replacement of gears and motors is less, and electric bicycles are effectively reduced. The maintenance cost; and the brush motor can achieve easy manpower riding through the overrunning clutch and the flywheel. Brush motors use brush mechanical commutation.
Project Overview
The Ameya360 brush motor solution employs mechanical commutation, magnetic poles, and coil rotation. The stator of the motor is equipped with a fixed main magnetic pole and a brush, and an armature winding and a commutator are installed on the rotor. The power of the DC power supply enters the armature winding through the brush and the commutator to generate an armature current. The magnetic field generated by the armature current interacts with the main magnetic field to generate an electromagnetic torque, which causes the motor to rotate to drive the load. The speed regulation process is to adjust the voltage level of the motor power supply.
The adjusted voltage and current are converted by the commutator and brush to change the strength of the magnetic field generated by the electrode and achieve the purpose of changing the rotation speed. During the rotation process of the commutator, it cooperates with the brush to form several switches, switching the direct current into several sets of ordered electrical pulse sequences, completing the process of DC to AC, which is the inverter; Frequency conversion: both change the switch To switch the rate, the higher the switching rate, the higher the frequency, and vice versa. The frequency conversion of the brush horse is a feature that has a simple structure, a long development time, and a mature technology, and is transformed with the transformation of the motor speed.
