Abstract
Methods, systems, and devices for electric machine torque adjustment based on waveform multiples are disclosed herein. One electric machine controller, arranged to direct pulsed operation of an electric machine, utilizes a pulse controller that calculates a first average measured torque from sensed torque values over a first time period and a second average measured torque from sensed torque values over a second time period, wherein the first and second time periods are different time periods.
Claims21
An electric machine controller arranged to direct pulsed operation of an electric machine, wherein the electric machine controller utilizes a pulse controller that calculates a first average measured torque from sensed torque values over a first time period and a second average measured torque from sensed torque values over a second time period, wherein the first and second time periods are different time periods.
An electric machine controller arranged to direct pulsed operation of an electric machine, wherein the electric machine controller utilizes a pulse controller that calculates an average torque based upon a time period that corresponds with a non-integer multiple of a waveform cycle or sub-cycle of a pulse waveform.
A system comprising:
- an electric machine;
- a power converter;
- and
- an electric machine controller arranged to direct pulsed operation of an electric machine, wherein the electric machine controller utilizes a pulse controller that calculates a first average measured torque from sensed torque values over a first time period and a second average measured torque from sensed torque values over a second time period, wherein the first and second time periods are different time periods.
A method, comprising:
- providing an electric machine controller arranged to direct pulsed operation of an electric machine;
- and
- calculating, using a pulse controller, an average torque;
- wherein the average torque is based upon a time period that corresponds with a non-integer multiple of a waveform cycle or sub-cycle of a pulse waveform.
