Motors for VFD drives |
| Stark motors suitable to run with vfd’s,
we offer the entire range of motors suitable to run with vfd.motors are
suitable for |
| |
|
|
Constant torque applications like crane, hoist,compressors etc |
|
Variable torque applications like
centrifugal pump , fan, blowers etc |
|
Constant power applications like lathes
winding machines |
|
Entire textile applications. |
| |
Motors for constant torque application suitable for speed range
of 1:10,1:5,1:2,etc can be provided. Depending upon the speed
range , motors can be offered with forced cooling (IC 416). Forced
cooling arrangement is available from 71 frame.the insulation is
suitable for VFD’shaving a minimum rise of 0.5μs. a special
insulation scheme is offered for lower rise times between 500v to
690v.
|
| Shaft induced voltages occur due to the use of vfd.this causes
flow of currents through the bearings which can lead to
premature bearing failure, insulated bearings can be provided on
request. We can provide encoder mounting on the non drive end
shaft on request. |
