Description:
l The control board is a sensored brushless controller, which is not suitable for non-inductive motors
l There are three specifications. There are two types of non-function button board which are used on the Wickers wu175 brushless drill. The switch cable has four-wire and six-wire. The four-wire switch cable has been welded. Another type of button board with function is used on WU292 or exported WU278/WU292 machines, which is different from the domestic WU278. There are three gears, no reversal and automatic stop function. The control board controls the Vickers WU175 and WU278 brushless motors to rotate normally.
l The controller consists of 6 40v195A imported high-power MOS tubes irlb3034 and a highly integrated ti main control chip. It is composed of DRV91680.
l This controller is small in size, but it can carry a large current.
l Controller voltage is DC14-20V, the main control power supply and the motor power supply can be supplied separately, the small blue line is the main control power supply, if it is higher than 21 volts, 7815 voltage stabilizer tube must be added before the main control power supply, the maximum withstand voltage of the MOS tube 40 volts, the highest should not exceed 36 volts.
Controller wiring method:
l T plug the blue wire to the positive, the thick black wire to the negative, the small black wire is for battery temperature detection, you can use this wire to change the temperature of the mos tube to prevent the mos tube from being burned out by overload. Three thick wires are connected to the motor, the wiring is Hall wire, red positive and black negative, the other three wires are phases. When connecting with Worx motor, the red wire is connected to motor U, the blue wire is connected to motor V, and the yellow wire is connected to motor W. Individual Worx motors will be different. Red and yellow must be reversed. The three-phase sequence must be correct when connecting with other motors, otherwise the motor Jitter does not turn or can turn the current is very large (Note: Do not use a power battery or high-power power supply to test before the connection is confirmed, otherwise it will burn the drive. When wiring, you must pay attention to the insulation of the wires. Hall wires and lighting wires will be damaged when they touch the power supply)
The control method of the potentiometer for the six-wire model:
l The thick blue and red line of the switch is a switch, and the six cables are for commutation control and speed control.
The four-wire model changes the potentiometer control method:
l The thick blue and red wire of the switch is a switch. The four wires are for commutation control and speed control. The yellow wire is connected to the smallest end of the potentiometer, the white wire is connected to the middle end of the potentiometer, the black wire is connected to the largest end, and the red and black are shorted to reversing.
