Working with three-phase power and motors that operate on three-phase power is confusing if you have never attempted it before. Three-phase power consists of three different AC power lines that differ in the timing of their peak voltage. ALWAYS USE WIRING DIAGRAM SUPPLIED ON MOTOR NAMEPLATE.
NEW ROLLED STEEL motor lines. FOR MOTORS WITH THERMAL PROTECTION.
Weg motor for low or high voltage.
You can search for your motor by model number.
The diagrams are presented as wiring diagrams with the numbers on the terminal leads. Low and high voltage three phase induction motors. M line - Squirrel cage rotor - Vertical.
Installation, Operation and Maintenance Manual . Examine the motor nameplate for wiring information. The nameplate will specify the motor voltages and may give specific wiring information.
Wire the motor for the appropriate voltage to . It will specify two voltages, one high and one low. Wire an Electric Motor to run on both 1and 2volts. Motors with six leads are nearly always.
Other Wiring Diagrams Available: Accessory Connection.
Two Spee One Winding, YD on High Spee Single Voltage. Lea Dual Voltage , WYE Connection. Part Winding Start (PWS) on Low Voltage. Each lead may have one or more cables comprising that lead.
In such case, each cable will be marked with the appropriate lead number.
An electrician demonstrates how to properly wire an electrical motor. Techtop Motor Connection Diagrams. NEMA Three Phase Wiring Diagrams (Reference Only). This is in the context of building wiring and the safety of electrical apparatus.
One of the most frequent customer complaints is “ low voltage.
Like “defective wiring ” in the fire investigation fiel “ low voltage ” takes the blame for many problems. Remember that whether motor voltage is “low” or “ high ” can only be judged at the motor terminals not at the control center, the bus, or the transformer .
