First, the classification of electric vehicle controller named
  The main function of the controller is to control the motor rotation speed, and the vehicle's electrical system for effective protection. According to the motor to be driven in the form of different parameters, to choose the controller parameters are also different. GB controller for electric vehicle named the following criteria:
  1, the controller named

Rated current (usually 2 digits)
Rated voltage (usually 2 digits)
  Product Code
ZK: brush motor drive controller with an ordinary type

Not the same as all the characteristics of the controller, and its inner workings are not the same, we were introduced following a variety of controller circuit structure and a typical circuit.
Second, the general structure and the general parameters of the module circuit
  1. Typical brush controller module circuit and schematic
  An ordinary brush block diagram of the controller as follows:

  Internal power supply controller internal electronics provide the operating voltage.
  PWM chip can switch to the occurrence of the input voltage output corresponding to a square wave pulse width of the MOS tube drive circuit.
  MOS tube drive PWM signal shaping circuit will provide MOS.
  MOS is a high-current switching element tube, and its on-time and off time, controlled by the PWM signal.
  Under-voltage protection circuit is reduced to the controller when the battery voltage below the set value, PWM chip to stop the PWM signal output, to protect the battery Buzhi Yu in the case of low voltage discharge.
  Limit protection (or over-current protection) circuit is the controller output to limit the maximum current to protect the battery, controller, motor, etc. will not be allowed to range over a large current.
  Representatives of ordinary brush controller model is ZK3610A, the typical circuit is as follows:

Brush control in terms of the ordinary, generally have the following general parameters:
  Nominal project uses reference
  Rated voltage matches the rated voltage of the battery used
  Rated discharge current allows the maximum current for a long time
  Undervoltage protection value in the protection of more than the battery voltage to the electrical power supply to allow
  Limit / overcurrent protection to allow the maximum discharge current of short
  Temperature control internal components can work in the temperature range
  Normal speed signal can be transferred to the transfer value of the signal voltage
  Brake brake signal when the signal level of gate potential
  According to the actual use of electric vehicles on the environment (such as temperature, etc.) and matching components (such as battery voltage, switch handles, brake handle, electrical power, etc.), select the appropriate controller parameters
  2. A typical brushless controller module circuit and the circuit
  An ordinary block diagram of brushless controllers are as follows:

Brushless controller in terms of the ordinary, generally have the following general parameters:
  Nominal project uses reference

  Rated voltage matches the rated voltage of the battery used
  Rated discharge current allows the maximum current for a long time
  Undervoltage protection value in the protection of more than the battery voltage to the electrical power supply to allow
  Limit / overcurrent protection to allow the maximum discharge current of short
  Temperature control internal components can work in the temperature range
  Normal speed signal can be transferred to the transfer value of the signal voltage
  Brake brake signal when the signal level of gate potential
  Motor phase to allow matching 60 ° / 120 ° phase angle of the brushless motor
  The parameters used to refer to the use of brush description of the controller parameters, should be emphasized that the phase brushless controller must be the same phase brushless motor, the motor can rotate.
