We offer sed 2100 speed control of fhp synchronous motor. We are offering sed 2100speed control of fhp synchronous motor using three phase vsi inverter .The variable frequency drive for synchronous motor, has advantage over variable voltage such as, (1) to vary speed in stepless manner(2) to maintain constant torquepower(3) to run motor on slower higher speed than ratedthe v.s.i. (voltage source inverter) drive is one methodto obtain the variable frequency voltage to control speedtorque of synchronous motorknow more
