Frequently Asked Questions
What speed does an 8 pole motor run at?
On a 50 Hz supply, an 8 pole motor has a synchronous speed of 750 rpm. Actual running speed is slightly lower due to slip under load.
What does B3 mounting mean?
B3 refers to an IEC foot mounted configuration where the motor is secured to a base or skid via mounting feet.
Is this motor suitable for continuous industrial use?
Yes. Motors of this type are typically rated S1 continuous duty, designed for long term operation in demanding industrial environments.
