Dual/Tap Wound Motors

Experts in Ventilation

Dual & Tap Wound Motors
Problem	Possible Cause	Recommended Action
High current draw and / or 'growling bearings'	Tap-wound motors can create problems if the 'star point' contractor is not connected. The motor will be fine in low speed but in high speed will have a high current draw and a severe electrical noise that sounds like noisy bearings. The motor will not last long when run in this condition. Dual-wound motors are rarely a problem.	Faulty wiring in the switchboard, check the correct contractor is connected.
