Brushless Motor Controller, DROK DC 6.5-50V Three-phrase Sensorless Motor Control Board BLDC Motor Driver Regulator 350W Motor PWM Duty Cycle Speed Controller Module with Heat Sink PLC Control Switch

Parameters:
Operation voltage range: 6.5-50V
Rated output current: 16A (If enhance cooling, can reach 25A.)
Max power: 350W
Over-current protective function: No (please add a fuse manually)
Motor stall protection: Yes
Over-temp protection: Yes
The highest rotating speed: 224000 RPM(2-pole motor), 74000 RPM(6-pole motor), 40000 RPM(12-pole motor), 35000 RPM(14-pole motor).
Dimension: 65*46*32mm

Wiring Ports:
1. U V W: Phase line output, connected to the motor
2. 5V GND: mainboard built-in power supply (the current cannot be exceeded 30MA)
3. VCC GND: the motor power supply (connect to external DC power supply)
4. SC: output pulse signal of rotating speed
5. DIR: forward and reverse control (can add a wire to connect external switch)
6. BRAKE: brake control (can add a wire to connect external switch)
7. 0-5V PWM: Speed control signal input (regulate speed by potentiometer; or regulate speed by switching signal input of 0-5V analog/PWM duty cycle via the switch jumper.

Notes:
1. It is recommended to add a fuse, as there is no fuses on the power supply circuit of the motherboard. The reversed connection will cause damage to some of the chip permanent.
2. Please do not artificially short circuit when the module is not working normally. Once short-circuit, it may burn the circuit board. For the first time testing, please use small current and low voltage, and increase the voltage and current when the motor is working normally. Please pay attention to the wiring connector to be insulated, and it is forbidden to hit the board parts with strong voltage.
3. Do not connect the drive motor which is with obviously inconsistent voltage, current, power, so as to avoid the unnecessary damage.

Package Includes:
1 x DC Brushless Motor Controller Board
