Electric motor has characteristic field stored as digital values for associating parameter and motor speed values, and microcontroller or microprocessor

Abstract: The motor (9) has its speed regulated by a variable physical parameter (2), especially a temperature. A characteristic field is stored as individual digital values for associating values of the physical parameter with corresponding motor revolution rate values. A microcontroller or microprocessor has access to the stored digital values. An Independent claim is also included for a method of regulating a physical parameter.

Device for vibration-isolating mount of a motor

Abstract: The vibration damping mounting is provided by a disc-shaped carrier element (12), with respective sections (24, 26) secured to the electric motor (2) and to a carrier (6) joined together via a number of elastic coupling struts (28). The struts allow limited radial, tangential and axial relative movement of the two sections. The relative movement is limited in all three dimensions by stops formed integral with the carrier element.

Speed controlling method and system for electronically commutated DC motors

Abstract: of EP0930698A system for speed control of DC motors, especially ones without collectors and controlled by rotor position sensors, has the motor current manipulated for speed changing in accordance with a control signal To manipulate the motor current, at least two different control procedures are used over the speed adjusting region of the motor With a certain transition speed or a transition value of the control signal corresponding to this, automatically passing over from one control procedure to the other one The magnitude of the respective transition speed of transition value of the control signal can be changed via an adjusting device
