Method and device for starting an electric motor

摘要

A method for starting an electric motor having a rotor, comprising the following steps:—driving the rotor with a first torque in a first rotational direction, wherein a maximum value of the first torque is not higher than a maximum countertorque acting counter to the rotation of the rotor, so that the rotor comes to a standstill in a first stationary position;—driving the rotor starting from the first stationary position in a second rotational direction that is counter to the first rotational direction until the rotor comes to a standstill in a predefined second stationary position; and—starting from the rotor in the first rotational direction starting from the second stationary position.

1. A method for starting up an electric motor, which has a rotor, comprising the steps of:
driving the rotor in a first direction of rotation with a first torque, wherein a maximum value of the first torque is not greater than a maximum counter torque opposing the rotation of the rotor, causing the rotor to come to a standstill in a first stationary position; starting from the first stationary position, driving the rotor in a second direction of rotation, which is opposite from the first direction of rotation, until the rotor comes to standstill in a predefined second stationary position; and starting from the second stationary position, starting up the rotor in the first direction of rotation.
