Deceleration method for electric motor involves switching generated current if rectifying value exceeds second predetermined value, and short circuiting motor if rectifying value falls below first predetermined value

摘要

The current in the electric motor (7) is measured. A rectifying value based on the measurement is compared with at least one predetermined value. If the rectifying value falls below a first predetermined value, then the electric motor is purposely short circuited. If the rectifying value exceeds a second predetermined value, the generated current is switched over a power consumption mechanism. An independent claim is included for a device for executing the deceleration method.
