BLDC Motor Controller, DROK Mini BLDC 3-Phase Brushless Sensorless Motor Driver Control DC 5V-12V 15W Speed Regulator Controller with Knob

Parameters:
Operating voltage: DC 5-12V(limit 15V)
Operating current: continuous 1.5A (peak 2A)
Control power: 15W (max rated value)
Static current: 0.005A (standby state)
PWM duty ratio: 1%-100%
Highest speed: about 10000r (depends on the motor )

Attention:
1. The motor controller is designed with input reverse connection protection. Please use it for motor with applicable parameters, or the chip will be burned. There is LED indicator if motor unmatched.
2. There are three-wire brushless motors and four-wire brushless motors, if used for three-wire brushless motor, three wires directly connect to the module terminals W, V, U separately, on need to distinguish order, but required solid connection. For four-wire brushless motor, there is a COM wire, which is no need to connect to the module. If connect, the module will be damaged.
3. Motors within 7200rpm, input voltage range is DC 5-12V, recommended input voltage with range of DC 5.5-6V for the first testing, then increase the voltage according to the motor working condition. For used motor with small internal resistance, recommend operating voltage DC 5-9V. Motor more than 7200rpm with small internal resistance, recommend operating voltage DC 5-7V, input 12V will burn the module.
4. Please offer pure DC power supply, it will be better to offer current more than 1.5A, the quality of the power supply will influence the performance of the driver module. If the motor cannot start or start difficultly for the power supply, please try another power supply.
