55kW 6 Pole IE3 (1000rpm) Teco AC Motor, IE3, B5 Flange Mounted, Cast Iron, Frame 280M
MPN: C2---55-6B5
Alt. SKU: C2556B5
Why Choose the TECO C2-55-6B5 55 kW 6 Pole AC Motor?
The TECO C2-55-6B5 is a heavy duty three phase squirrel cage induction motor engineered for continuous industrial service where reliable torque and reduced operating speed are required. Built with a rugged cast iron frame and supplied in IEC B5 flange mounted configuration, it is designed for direct coupling to pumps, compressors and process machinery.
The 55 designation indicates a rated output of 55 kW, while the 6 pole configuration provides a nominal speed of approximately 1000 rpm at 50 Hz. This makes it well suited to applications demanding strong torque at moderate speeds. The B5 mounting style enables secure flange mounting directly to driven equipment in accordance with IEC standards.

Frequently Asked Questions
What speed does a 6 pole motor run at?
On a 50 Hz supply, a 6 pole motor has a synchronous speed of 1000 rpm. The actual operating speed is slightly lower under load due to slip.
What does B5 mounting mean?
B5 is an IEC flange mounting configuration where the motor is secured via a large mounting flange for direct coupling to driven equipment.
Is this motor suitable for continuous industrial operation?
Yes. This motor type is typically rated S1 for continuous duty and is designed for long term industrial service.
