an Sir/Madam

an i have a dayton a.c. shaded pole single phase motor with 1/150HP,
an 3000
an RPM, 230 V, 60 Hz frequency and Full Load Amps
an 0.24 . I want to control the torque of this motor through program.For
an that i have feedback from motor is current to the motor . I want to
an control the torque use this current as feedback.for that I need a
an equation connecting torque and the current.

RPM of this motor type is dependant on frequency. Altering the voltage
will only give approximately 10% practical change in torque.

A*s*i*m*o*v

.... Engineers do it to maximum stress loads.
