How to measure an electric motor with a multimeter
Measuring controller: turn on the power, turn it, the power and Holzer power should be 4 - 5V voltage, the controller of the three Holzer line potential should be the sameThis is a simple method of measurement,The motor does not turn, usually the circuit fault is in the majority, and next is the brake handle, turn the handle. In the second is the controller, the motor is generally not damaged
Disconnect the controller and motor lead: three phase lines should be interlinked, the resistance is very small, if the motor bearings are not bad, the lead is not worn, there will be no problemDisconnect the motor controller and measuring range measuring diode lead: Holzer, the red pen is connected with the motor leads to fine black, black pen followed by yellow green blue, there should be 50 - 300 ohm resistance value, and the three line resistance is not greater than 20, Holzer is normal.
Brushless motor has 8 lead, three thick is phase line, five thin is Holzer line, red and black is power supply, yellow green blue is signal output.
