Motor
The most important accessory of an electric bicycle is the electric
motor, which basically determines the performance and grade of the
vehicle. The motors used in electric bicycles are mostly
high-efficiency rare earth permanent magnet motors, which are
mainly divided into three types: high-speed brushed teeth+wheel
reduction motors, low-speed brushed motors, and low-speed brushless
motors.
A motor is a component that converts battery energy into mechanical
energy and drives the rotation of electric vehicle wheels. There
are many types of motors used in electric vehicles, including their
mechanical structure, speed range, and electrification form. Common
ones include: brushless toothed wheel hub motors, brushless toothed
wheel hub motors, brushless toothed wheel hub motors, brushless
toothed wheel hub motors, high disk motors, side mounted motors,
etc.
BRUSHLESS DC MOTORS
The mechanical switching of current associated with brush motors is replaced with electronic switching in brushless motors. Brushless DC motors are not simply AC motors powered by an inverter, instead these devices use rotor feedback devices so that the input wave forms are kept in proper timing with the rotor position. Some form of electronic commutation switching is necessary for all motors, except in the limited angle devices. Brushless DC motors with suitable control electronics can be directly substituted for similarly-sized brush DC motors.
Brushless DC motors provide several advantages:
1. Brushless units may be operated at much higher speeds and at full torque at these speeds, resulting in a motor with considerable power output for its size. High speed operation is especially difficult for conventional brush DC motors because the high energy that must be switched by the brushes is destructive and shortens motor life. In brushless motors this energy can be handled by the drive circuits.
2. The stator, which contains the motor’s windings, may be mounted in a substantial heat sink to minimize temperature rise and prolong bearing life.
3. Where long life is a requirement, the absence of brushes normally increases the motor’s life expectancy to that of the bearings.
4. In high-cleanliness applications, unacceptable brush wear particles are eliminated. 5. The EMI (Electromagnetic Interference)normally associated with the arcing of the brush commutator inter-face is eliminated in the brushless motor. Brushless DC controllers are generally free of major EMI contributors.
6. For explosive environments, a brushless motor can be used without special housing elements necessary to explosion-proof a conventional DC motor.
7. Although brushes have been used extensively in space environments, their preparation is expensive and time consuming. The brushless motor requires much less preparation.
