The magnetic gear is a magnetic coupling device that renders a mechanical ratio between two magnetically-coupled devices such that: They have a ratio of rotational or translational movement between input and output, which may be 1 in the case of a pure magnetic coupling or one of many gear ratios in a magnetic gearbox.
In addition, an on-shaft permanent magnet motor drive system also utilizing gas turbine Prime Movers on the main reduction gear, can also provide electricity when driven by the Prime Movers. The on-shaft permanent magnet electric motors provide propulsion at lower speeds via on-board electrical power generation gas turbine or diesel, at ...

The rotor is made of permanent magnet. Small synchronous motor with integral stepdown gear from a microwave oven A synchronous electric motor is an AC electric motor in which, at steady state , [ 1 ] the rotation of the shaft is synchronized with the frequency of the supply current ; the rotation period is exactly equal to an integer number of ...
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.
Additionally, soft magnetic material with many teeth on the rotor and stator cheaply multiplies the number of poles (reluctance motor). Modern steppers are of hybrid design, having both permanent magnets and soft iron cores. To achieve full rated torque, the coils in a stepper motor must reach their full rated current during each step. Winding ...
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt. [1] [2] [3] [4]
Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the stator slots of a permanent magnet machine. It is also known as detent or no-current torque. This torque is position dependent and its periodicity per revolution depends on the number of magnetic poles and the number of ...
