Turn the circuit breaker off again. The new Brushless motor is maintenance-free, highly reliable and has a life of 20,000+ hours.

New DC Brushless Motor. How To Use a Multimeter to Test a Pool Pump Motor - Winding Resistance WRITTEN BY: ... To test the upper main windings, place the meter probes on A on the power terminal, and on the end of the yellow wire attached to terminal 3 of the Overload Protector. At 17 September 2014, 1:07:57 user bulelani wrote: [reply @ bulelani]; I was doing my trade test, motor test task. The mulitmeter should read "OK." This means that the 3-phase motor is turning in the correct direction and running correctly. The first check to see if the armature windings are shorted is the “180-Degree Resistance” test.
Check the motor start capacitor start. Checking Compressor Windings Using Multi Meter As you know that in single phase fridge or air conditioner compressor we have internally instill a single phase motor which consist two types of winding which we called main winding (ruining winding) and Auxiliary winding (starting winding). Switch the position of two of the wires — the order doesn't matter — then reattach the mulitmeter leads to the wires. If the motor hums loudly but fails to start under load and the ammeter indicates a current draw of six to 10 times the motor's FLA rating, the problem could be a bad start capacitor, a start switch stuck in the open position or an open start winding. You can use a multimeter to check the voltage and amperes your motor … The windings (all three in a three-phase motor) should read low but not zero ohms. The smaller the motor, the higher this reading will be, but it should not be open. Touch the red (positive) lead of the multimeter to the positive end of the wire windings around the motor. Record the reading. Here are three quick checks you can perform with a volt/ohm meter to test a DC motor armature winding to determine if a motor armature is functioning properly. This guide will hopefully make testing fan motors for you easy, regardless of your experience level or type of fan motor that you are testing. The first check to see if your armature windings are shorted is the “180° Resistance” test. Touch the black (negative) lead of the multimeter to the negative end of the wire windings around the motor. Depending upon brush size, this may allow access to the commutator without removing the armature from the motor. Turn on the motor. Now I had to balance the windings, I had 21.3 on U and 10 on V but infinity (OL) on W windimg. If the winding's insulation wears away near the motor's case, the bare-wire winding shorts to ground. Introducing a robust DC Brushless Motor and gearbox combinations. Fix the reversed power feed by first turning off the motor and unplugging it. A volt/ohm meter is used to check the resistance of the series windings connected between the two commutator bars of each coil.

The flow of electricity into the windings creates an electro- magnetic field which the magnets try to repel and the motor starts to turn.

If the shaft turns freely, set the multimeter to its ohms function to check resistance. It will usually be low enough (under 30 Ω) for the audible continuity indicator to sound. How to Test a Fan Motor With a Multimeter It can sometimes be very confusing to test fan motors for people who don’t have much experience. As always, make sure to disconnect all power from machine before doing anything. The wire in the windings use an insulating covering as an isolation barrier. I found out my windis are not da same while doing continuity test with my meter.

A volt/ohm meter can be used to check the resistance of the series windings connected between the two commutator bars of each coil. A motor fails when its windings short to ground, short to each other, or open--a break in the winding's wire. Depending upon brush size, this may allow access to the commutator without removing the armature from the motor. The reading that appears on the multimeter screen is the resistance in ohms.
