Abstract
The invention relates to a method for monitoring a transmission driven by an electric motor with a motor control, in which load changes with zero crossing of the motor torque in the transmission are monitored, wherein at least one operating parameter of the electric motor and/or the motor control is measured and evaluated for monitoring the load change.
Claims13
A method for monitoring a transmission driven by an electric motor with a motor control, comprising:
- monitoring load changes with zero crossing of motor torque in the transmission by measuring and evaluating at least one operating parameter of the electric motor and/or of a controller of the electric motor, wherein a number of load cycles exceeding a predetermined number of load cycles is detected as a critical operating state.
Method A method for monitoring a transmission driven by an electric motor with a motor control, comprising:
- monitoring load changes with zero crossing of the motor torque in the transmission by measuring and evaluating at least one operating parameter of the electric motor and/or of a controller of the electric motor, wherein a frequency of load changes is monitored and exceeding a predetermined frequency is detected and signaled as a critical operating state.
