Benefits of technology

This design enhances efficiency and cleanliness by reducing noise and vibration, maintaining constant magnetic force for stable operation and allowing for single-phase AC drive, suitable for low rpm high-torque applications like wheel hub motors.

Problems solved by technology

However, prior art systems still can be difficult to install, and cause drag due to the presence of magnetic fields.
The magnets also attract and collect road dust and debris, causing the motor to become dirty and inefficient.

Embodiment Construction

[0032]The present invention is an improved hybrid drive apparatus comprising a switched reluctance hub motor, as shown in FIGS. 1 and 2. By using a switched reluctance motor, the present invention has the advantage of eliminating any drag caused by the existing magnetic fields of the motors used in the prior art by turning off the magnetic fields when not being used. The present invention also has the advantage of being cleaner and more efficient to operate, where any magnetic road dust or debris attracted during operation is dropped or repelled when the magnetic fields are turned off.

[0033]The switched reluctance motor is a type of reluctance motor (i.e., an electric motor that runs by reluctance torque). Unlike common DC motor types, power is delivered to windings in the stator rather than the rotor. This greatly simplifies mechanical design as power does not have to be delivered to a moving part. However, some sort of switching system needs to be used to deliver power to the diff...

Abstract

An improved hybrid drive apparatus with a switched reluctance hub motor. The switched reluctance motor eliminates any drag caused by the existing magnetic fields of the motors used in the prior art by turning off the magnetic fields when not being used. It also is cleaner and more efficient to operate, as any magnetic road dust or debris attracted during operation is dropped or repelled when the magnetic fields are turned off. An improved switched reluctance motor may be used, with a stator ring and rotor ring designed so that the low reluctance flux path does not pass through the full diameter of the rotor or rotor bars. Dual stator rings may also be used.
