Any motor that matches those specs will work.

Look for a frame size. It could easily be 56 or 56H. If so, any manufacturers similar frame size will fit. If it's 56HZ, it has a 7/8" shaft instead of a 5/8". a 56 frame will fit where a 56H was, a 56H will very likely fit where a 56 was. The 56H is a bit longer, and it has holes drilled to match 56 frames as well as another set of holes further back.

Since you're having trouble with motors, I'd use a 1HP model. It sounds like the 3/4HP is overloaded.

Also, there are two common kinds of cooling. ODP (Open Drip Proof) and TEFC (Totally Enclosed Fan Cooled). The TEFC ones have a cooling fan on the back, the ODP one have a cooling fan inside.

Make sure the fan turns the right way. Most fans will still move air if they're backward, but they'll overload the motor.

Finally, make sure the motor is connected for the correct voltage.

Thanks,the frame size is 56,do you means I can use 1HP motor instead?
That motor I bought,it don't running on low voltage,and on high voltage the fan was turn on right way,only one things different is the AMP is 11.0/5.4,the old one is 11.4/5.7,is it the reason cause it overload?

Frame size, voltage and speed need to be the same. Watch the "C" dimension as the new motor could be longer and not fit.
