2 Speed Three phase motor
2 Speed Three phase motor
(OP)
Hi,
I'm actually have zero knowledge in motors. But, I'm wondering is it possible to configure/set up a three phase motor to having 2 different speed? I'm trying to make a machine for shear forming that require 2 different speed for roughing and finishing.
Best regards,
Picks

RE: 2 Speed Three phase motor
There are also motors with two complete, separate windings and the speed ratios do not need to be a 2:1 ratio.
But, it may be cheaper and result in a better product if you use a Variable Frequency Drive and a standard motor. You will have a very wide speed range and will be able to run smaller three phase motors from a single phase source.

Will it be durable and reliable if the speed is switched between high and low frequently, for instance 1 cycle is 1 minute and for 500 cycles a day? (minimum)

Things to note
1. The motor winding is suitable for VFD duty.
2. May be an additional external cooling fan for the motor since its own shaft mounted fan may not be enough at low speed.
