Firstly, I apologies for having to ask such a basic question.
I'm looking to buy a controller for a permanent magnet motor. The specs of the motor are: 200VDC, 1.5HP, 5700RPM, 7.6A, form factor: 1.0
I am trying to decide between two controllers that I have seen on ebay:
The cheaper one has the following specs: DC 0-220V (output), 4A, 500W
The more expensive has these specs: DC 0-220V, 8A, 800W
My question is: what will happen if I tried to run the motor with the first controller?
The motor draws 7.6A but the controller is rated at 4A. Will it run at half torque? Will the motor cause damage to the controller/vice versa?
(...or am I better off getting the 800W controller?)
