6 FAQs about [Measure the resistance of the energy storage motor]

How to measure insulation resistance?

To measure insulation resistance, a DC voltage of 500V or 1000V is applied between the windings and the ground of the motor as shown below: During the measurement and immediately afterwards, do not touch any terminals of the motor as some of them carry dangerous voltages that may be fatal.

How do you measure a BLDC motor?

If it is a WYE connected BLDC motor, the resistance is the line-to-line resistance. Thus divide the resistance(l-l) by 2 to get the phase resistance. To measure the Ke of the motor, put the motor shaft in a lathe and rotate the shaft at some speed [rpm] such as 1000rpm. With a dc motor, use a dc voltmeter to measure the armature voltage.

What is the minimum insulation resistance of a motor?

During the measurement and immediately afterwards, do not touch any terminals of the motor as some of them carry dangerous voltages that may be fatal. The minimum insulation resistance of motor measured to ground at 500V can be measured at a winding temperature of -15°C – 20°C.

What is a BLDC motor ohmmeter?

Brushless dc motors (BLDC) are 3 phase synchronous motors used in a configuration to be treated as dc drives. For the winding resistance use an ohmmeter. For a dc motor measure the resistance between the 2 armature wires. If it is a WYE connected BLDC motor, the resistance is the line-to-line resistance.

How do you measure a motor Ke?

To measure the Ke of the motor, put the motor shaft in a lathe and rotate the shaft at some speed [rpm] such as 1000rpm. With a dc motor, use a dc voltmeter to measure the armature voltage. The Ke is then the voltage you read divided by the speed in rad/sec. Convert rpm to rad/sec as- rev 2 π radians min rad
