Wye motor in delta power system
Wye motor in delta power system
(OP)
I've supplied several motors on a project (in USA) that utilizes a delta power system. Most/all of my low hp motors appear to be wye wound. The client believes all motors must be delta wound for use in a delta power system.
Their reasoning is that when a wye only wound motor is connected to a delta power source, it carries only 67% voltage across the winding, providing less horsepower. Under full load operation, the motor is more likely to fail.
Can a wye wound motor can be used in a delta power supply? Why or why not? Thank you.

I'm told my client will accept wye wound motors where the motor winding is not grounded. Isn't this inherent to wye wound motors? Are there problems using a wye wound motor with grounded winding in a delta power system?
