Abstract
Electrical sub-assembly and associated method of operation There is provided an electrical sub-assembly having first and second motors, the second motor being a reluctance motor. Each of the first and second motors has a respective rotor drivingly connected to the other and is independently operable to generate torque either alone or in combination with one another. The torque generated by each of the first and second motors may be transmittable to a drivetrain of a vehicle. As such, the electrical sub-assembly may have particular application in a hybrid or electric vehicle.
Claims22
An electrical sub-assembly comprising:
- a first motor;
- and
- a second motor
- wherein each of the first and second motors is a reluctance motor having a respective rotor drivingly connected to the other and each of the first and second motors is operable to generate torque either by the first motor alone or by both of the first and second motors in combination with one another.
(canceled)
A method of operating an electrical sub-assembly comprising:
- operating either one or both of a first motor and a second motor, each of the first and second motors being a reluctance motor having a respective rotor drivingly connected to the other, to generate torque either by the first motor alone or by of the first and second motors in combination with one another.
(canceled)
A controller for an electrical sub-assembly, the controller configured to:
- operate at least one of a first motor and a second motor to generate torque either alone or in combination with one another;
- receive an input indicative of speed and/or torque of at least one of the first and second motors;
- and
- control operation of at least one of first and second motors in dependence on the input by use of a function relating the input to efficiencies of at least one of the first and second motors.
