How fast can a dryer motor spin?

Answer 1

it depends on the type and model of dryer and also what type of motor is used

for induction motor you can calculate the RPM

A squirrel cage induction motor is a constant speed device. It cannot operate for any length of time at speeds below those shown on the nameplate without danger of burning out.

To Calculate the speed of a induction motor, apply this formula:

Srpm = 120 x F

P

Srpm = synchronous revolutions per minute.

120 = constant

F = supply frequency (in cycles/sec)

P = number of motor winding poles

Example: What is the synchronous of a motor having 4 poles connected to a 60 hz power supply?

Srpm = 120 x F

P

Srpm = 120 x 60

4

Srpm = 7200

4

Srpm = 1800 rpm
