Results
- Synchronous speed
- 1500 rpm
Actual induction motor speed differs because of slip. This calculation does not determine allowable mechanical speed.
Formula & guidance
ns=120f/poles
Actual induction motor speed differs because of slip. This calculation does not determine allowable mechanical speed.
Change the example inputs and check each field’s units. Use equipment datasheets and applicable project standards for final decisions. Results do not establish Canadian electrical-code compliance or certify a design.
