## The basics of electrical troubleshooting Electrical Construction

How to Troubleshoot 3 Phase AC Motors. ~ Learning Electrical. The modern electric motor installation the individual motor drive has practically replaced all other types. It is comparatively easy to obtain the required speed through the use of motors directly connected to the driven machine, through speed reducers, or the now more economical geared motors, or even through V-belt or chain or sprocket drive., However, it may be required to continually check on the future voltage that is being supplied to the motor. In a three phase motor, which are most commonly used for commercial purposes, the amount of power drawn by a motor must be equal from all the phases. Any imbalance can cause a problem. If there is an imbalance of more than 10% between any.

This is a BRIEF COURSE INTENDED TO ACQUAINT YOU WITH BASIC electric MOTOR TROUBLESHOOTING AND testing. CAUTION. If you have not been trained in how to work safely near live electrical circuits, do not attempt to measure line voltages.

Three-phase motors are normally used in commercial-type operations. These motors have fewer parts and are more sturdily built than their single-phase counterparts. As a result these motors are less prone to malfunctions and tend to operate for many years. Because of their industrial use, if they are receiving the correct voltage, they are Identifying Motor Defects Through Fault Zone Analysis By Noah P. Bethel ELECTRICAL maintenance personnel have for years been limited to troubleshooting with no more than a fluke and a Megger. This unfortunately does not provide enough information to allow most electricians to feel totally confident in

AS-184 3 Wire 3 Phase Motor Schematic shows reversal diagram for a 4 wire reversible PSC motor using a triple pole double throw switch. AS-183 Triple Pole Double Throw Switch. Load too high Verify that the load is not jammed. If the motor is a replacement, verify that the rating is the same as old motor. If the previous motor was a special design, a stock motor may not be able to duplicate the вЂ¦ motor. вЂў Measure between each individual motor lead or terminal and the motors armature. If the multimeter reading is not open (O.L.), replace the spindle motor. If the motor is cool but alarm persists, check Parameter 278:14. If the parameter is correct, replace the motor sensor with P/N 33-7500A. Spindle Motor - Troubleshooting Guide Page 3
