What is peripheral speed in motor?

Peripheral speed (Ps) refers to the speed on the periphery or the circumference of the rotor. The peripheral speed is given by the product of the circumference (2πR) and the speed (RPM). ∴ Ps = π × D × RPM (∵ 2R = D) The peripheral speed is dependent on the speed as well as the diameter of the rotor.

What is the maximum value of the peripheral speed that should not exceed?

For a normal design, the diameter should be so chosen that the peripheral speed does not exceed about 30m/s
