A rotary tilling apparatus separates a power transmission system starting from a flywheel to a passive movement device through an elastic coupler from another power transmission system starting from the flywheel to a rotor of a motor generator, and thereby reduces a load applied to the rotor and prevents the power transmission system of the passive movement device from providing a negative effect to an engine and the rotor. A parallel hybrid power transmission mechanism includes an engine, a crank shaft disposed on the engine, a motor generator, a passive movement device configured to receive a motive power of the motor generator, an input shaft disposed on the passive movement device, a flywheel coupled to the crank shaft, an elastic coupler configured to couple the flywheel to the input shaft, and a rotor disposed on the motor generator and coupled to the fly wheel.

An apparatus for cooling a motor of a hybrid vehicle includes a support ring that is disposed between a motor casing and a motor and has a shape that encloses the motor. A water jacket is formed in the support ring and circulates cooling water and an oil jacket is formed in a support ring and circulates oil. Further, oil is discharged from the oil jacket is sprayed onto the motor to enable the oil to be used to cool the motor and to enable cooling water to be used to cool the motor. Accordingly, the performance of cooling the motor is enhanced.

The present disclosure relates to a transmission system having a transmission subsystem, a transmission housing for housing the transmission subsystem, and a rotor operably associated with the transmission subsystem. The rotor has a weight and dimension to act as a flywheel. At least one stator pole segment is housed within the transmission housing and has at least one stator winding thereon positioned in proximity to a surface of the rotor. An inverter communicates with the stator winding and electrically energizes the winding to cause rotation of the rotor.
