Electric bicycle motor controller principle

Car fast motor controller pace of development in recent years, is hard to imagine, operating on increasingly "fool", and the display is more complicated. Drive connection, it also has an electric mountain bicycles performance and help functions, if the conversion to boosting state, with the chain tension dynamometer, or axis torque sensor, tandem electric bicycle pedal motion as long as the pedal, you can perform or help determine the booster's size.
The controller is a peripheral device and the main chip (or single-chip) components. SCM also called microcontrollers, are integrated on a single chip to memory, language has transformed signal decoder, sawtooth generator and pulse width modulation function circuit and make the power MOSFET switching circuits on or off, by side wave conduction time of the power control tube drive circuit to control the motor speed, integrated input and output ports, and the computer chip composition.
Design quality control, features, functions used in microprocessor, power switching devices and peripheral devices circuit layout is directly related to vehicle performance and operational status, also affect the performance and efficiency of the controller itself. Different quality controllers, used in the same car with the same state with the same set of battery charge and discharge, and sometimes show large differences in driving ability.
