Check all three wires singly T1,T2,T3 (all three phases) to the ground wire. Readings should be infinite. If its zero or reads any continuity at all, then a problem exists with either the motor or cable . If it is go directly to the motor and disconnect from cable and check motor and the cable separately.
Keeping this in view, how do you know if your engine is good?
Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a zero reading or any continuity reading, you have either a motor problem or a cable problem.
Also Know, how do you troubleshoot an electric motor? 2. Motor Has Been Running, Then Fails to Start
- Fuse or circuit breaker is tripped. Replace the fuse or reset the breaker.
- Stator is shorted or went to ground (Motor will make a humming noise and the circuit breaker or fuse will trip)
- Motor overloaded or jammed.
- Capacitor (on single phase motor) may have failed.
how do you test a small motor?
Ensure it is set to measure volts as multimeters. It can also measure amperes and ohms. Place the copper sensors running from the multimeter onto the metal terminals on the small electric motor. The sensor on the end of the red wire from the multimeter touches the terminal that has a red wire attached.
How do you troubleshoot a 3 phase motor?
How to Troubleshoot a 3-Phase Electric Motor
- Take input voltage to the motor using the volt ohmmeter. The motor-specified voltage must be present on all three phases.
- Examine the motor’s electrical connections and terminals.
- Remove motor voltage and disengage the motor from the machine that it is running.
- Check the motor for heat or burnt smell.
