A GENERATOR FOR VEHICLES

Permanent magnet conical motors, stators and rotors thereof

A permanent magnet conical motor comprises a stator whose inner surface has a cone shape and a rotor having a truncated cone shape where a cone angle of the rotor is the same as a cone angle of the stator. The rotor may have a permanent magnet and rotate axially with respect to the stator. A spring mounted on a shaft of the rotor may negate an axial force produced by the magnet when the motor is not energized. The spring elasticity coefficient may be based on the axial force produced by the magnet when the motor is at no load. The cone angle may be calculated based on torque demand and an axial force required for an axial movement. When energized, a force acting on the rotor has a normal component and a tangential component with respect to a rotor lateral surface, and the tangential component may be proportional to rotor torque and a shear stress produced on the surface. The rotor axial force may be determined according to magnet characteristics at no load, and the magnet characteristics ...

ENERGY ABSORBING SHOCK MECHANISM FOR REDUCING IMPACT AND ROTARY ACTUATOR INCORPORATING SAME

A shock absorber for a shaft. The shock absorber comprises a collar having an opening receiving the shaft. A clearance gap is defined between the collar opening and the shaft. A pin offset from the axis connects the collar to a shoulder on the shaft. A resilient o-ring arranged in the clearance gap engages the collar and the shaft. In operation, the collar and the shaft rotate in unison. However, when the collar accelerates or comes to a sudden stop, the resilient o-ring compresses to provide the shock absorption. The shock absorber may be incorporated into a rotary actuator. In a rotary actuator, the collar includes a stop tab that rotates between two stop surfaces of the actuator housing. When the stop tab strikes one of the stop surfaces, the resilient member compresses thereby absorbing and reducing impact force. Compression in the resilient member is snubbed via mechanical stops.
