Abstract (en)
[origin: DE19730047A1] The invention uses a small D.C. motor as a base the winding of which is designed to allow a high idle rate with a simultaneous high starting torque. Thus a motor with a characteristic speed curve (3) having a steep slope is provided. Through speed control or regulation, in particular by electric impulsion modulation, a motor flat characteristic curve (5) or a motor characteristic curve (7) with a particular pattern can be obtained from the speed characteristic curve having a steep slope. Said motor (5, 7) characteristic curves could only be obtained in the past with a proportionally bigger and heavier motor.
