DC motors with excitation winding

In the case of electrical excited DC motors the magnetic field of the stator field is generated using an electroagnet. Wattage of 5 to 2.000 W. Voltages of 12 to 180 V – other voltages on request.

For ESTAN shunt motrs the excitation winding is located parallely to the armature winding. With this kind of excitation, the rotation speed remains almost the same.

APPLICATION

• wherever a constant rotation speed is required, for example for tractive units, starters for vehicles, etc.

BENEFITS

• high efficiency
• strong tightening torque at rotation speed zero
• simple speed variable
• linear rotation speed torque behaviour
• compact type for example B3, B4, B14
• isolation class possible up to H
• protection class up to IP65
