Thanks for the replies but no real good suggestions yet. All the winding are equal in resistance . no grounds , since it is a capacitor start motor if it starts in low speed then the cap is good right . It is a original installation motor and the switch was replaced then these problems arise of...
Lafert ac motor single phase 2 speed with 2 groups of leads for the windings. It is a capacitor run motor with no start winding . 3 leads to each speed and no centrifugal switch . I am unable to get high speed to run at rated speed . runs but at low speed with a hum noise . I can not get...
DO the start and run windings of the slow speed add on to the high speed winding to get the high speed . I have connected this lafert single phase motor but the high speed is the same as the low and it makes a humming noise when swithced to high . No diagrams or identified leeds . Do i have to...
