| Advantages of 'Mark' D.C.
MOTORS |
|
| |
Lower Excitation Power
(Field Power) |
|
Low operating
temperature due to lower heating of the
field. |
| |
Energy
Saving in field Power Excitation |
| |
Compensating
winding provided from 0.07 KW onwards |
| |
Suitable
for High di/dt Ratios and Start/Stops |
|
Totally sparkless
commutation over entire range |
|
Enhanced Brush
Life. |
|
Large size
commutator resulting longer commutator life |
|
Large and
sturdy CI Frame |
|
Bigger bearing
size for equivalent HP Ratings |
|
Easy Maintenance
due to spacious design |
|
Blower ratings
small. Additional power saving |
|
No Blower
cooling upto 2.2 KW hence problems due to
Blower Motor failure are absent |
