Now, for us, e-bike is not only a means of transportation, but also a symbol of green travel. Electric bikes are popular because they have an advantage over ordinary bikes in terms of speed. The new magnetic contact charging does not need to be plugged in, and the light touch charging makes charging faster and more reliable.
At present, permanent magnet synchronous motor is the mainstream motor of new energy electric vehicle electric drive system.
Because compared with other motors, permanent magnet synchronous motor has the following advantages:
High power density, high torque density, can provide effective starting torque when the car starts, to meet the needs of car operation;
Simple structure, high reliability, permanent magnet synchronous motor use permanent magnet instead of excitation coil, more streamlined structure, improve the new energy vehicle motor technology, improve the reliability of motor operation;
Small and lightweight, the volume, weight and consumables of permanent magnet synchronous motor with the same capacity are only about 70% of that of ordinary new energy vehicle motor;
High efficiency and energy saving, permanent magnet synchronous motor generates a magnetic field through the permanent magnet, drives the stator and rap to rotate, reduces the rotor resistance loss, improves the motor efficiency of new energy vehicles, is the most efficient motor.
In short, compared with AC asynchronous motor and DC motor, permanent magnet synchronous motor unit power consumption is small, unit power volume is small and light, can save more power, and save more space to install other equipment.
Therefore, permanent magnet synchronous motor is simply tailor-made for Electric bikes.
