Variable Frequency Drive is a controller that drives an electric motor. Normally when you supply the power to motor , an electric motor runs on fix speed but when it is required to change the speed of motor , Variable frequency Drive is used. It is also known as Variable Speed Drive, Adjustable Frequency Drives, AC drives , Inverter etc.
Frequency is directly related to the speed of motor . Speed Formula is as follows.
Speed ( RPM) = 120 F/P where 120 is constant and Pole is fixed at the time of designing of motor.
Only Frequency is only the element by changing it , we can increase or decrease the speed of motor.
We at Vardhman do repair of Variable Frequency Drives of every make and every capacity . Our trained and experienced engineers are capable to do repairing of any VFDs .We repair every make AC drives like ABB,Delta, Allen bradley ,Siemens,Yaskawa,L&T,Danfoss,Mitsubishi,INVT,Rexorth,Lenze,Baumuller ,Fanuc, Hass etc.
We also repair CNC machines spindle drives , axis drives & CNC controllers of FANUC , SIEMENS , HASS ETC.
We have sufficient stock of electronics components and due to that we are able to repair every equipments very fast.
