| The noise levels of the
motors have been calculated in accordance with DIN EN 21
680 and are well below the values permitted by EN 60034
- 9.
They have been
achieved both by means of design measures and by
optimising the magnetic circuit and the seperately
driven fans
|
| The blowers of D.C.
Motors have three phase motors with wide range of
winding and supply voltages. The blower motors are
selected strictly in accordance with the air quantity
required and ensures cool running of motors under the
specified operating loads / overloads. The terminal box
of blower motors are easily assessible. |

BRUSH MATERIAL COMMUTATION :
Practically sparkless commutation with converter feeding,
even under overload conditions is achieved. As a result,
the brushes have an extremely long life.
