Specification

Laminated Yoke 

Construction Range

Output: 1.2 kW to 450 kW 

Frames: 100 to 280

Brush Lifetime

Brush Material, Commutation:

Practically sparkles commutation with converter feeding, even under overload conditions is achieved. As a result, the brushes have an extremely long life.

Noise Level

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 optimizing the magnetic circuit and the separately driven fans.

At no load, with blower (50 Hz) on, with 3 Ph, 6 pulse thyristor supply to D.C. Motor (up to 2000 RPM)

Filter Mounting

A dry type air filter can be mounted or retrofitted on all the D.C. Motors without derating.

Forced Cooling Details

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 boxes of blower motors are easily assessable.
