Description
This Brushless Motor Controller DC 12-36V 500W PWM Driver Board is used for the 3-phase brushless sensorless motor, but not suit for all 3-phase brushless sensorless motors directly. If the driving effect is not good (such as starting jitter, reversing, the motor no-load working current is too large, the speed is not stable, the efficiency is low, and can’t start up with a load) Customers can adjust the resistance and capacitance of the driver board according to the actual situation to achieve the best effect.
Specifications and Features :
- Protection: Overload protection, locked-rotor protection, over-current protection
-
Analog voltage speed regulation: 0-5V
- Operating temperature: -40 ~ +85℃
- Drive power: ≤ 500W (related working voltage)
- Speed control function: voltage speed regulation or single-chip
- microcomputer control PWM speed regulation
Wiring Diagram:
Pin Connection :
5V -Driver board internal output voltage
Signal - Motor speed pulse signal output port, 5V pulse signal.
Control port:
Z/F- Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0 V low level or connect to GND is a reverse direction.
VR -Speed control port. Analog voltage linear speed regulation 0.1v -5V, The input resistance is 20K Ohm, connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle 0-100%
GND—Used for Drive board internal control.
Power port :
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND----DC-
VCC----DC +
3. Use shielded wires if the drivers' board has more than 50 cm distance from the motor, otherwise, it may lead to abnormal driving, affecting the normal use.
4.Control port distance: 2.54mm,Power port distance: 3.96 mm
5. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
Package Includes :
1 x Brushless Motor Controller DC 12-36V 500W PWM Driver Board
