Double the poles, halve the speed.
Constant toque or variable torque, these Dahlander two speed motors have it all.

This week at Byrne Electric Motors we had a selection of variable and constant torque versions leaving us this week.
The variable torque being used in a HVAC application and the constant torque being used on a conveyor system.
