摘要： Leakage of magnetic fluxes passing through the gaps between the magnetic pole teeth of an armature is reduced thereby to reduce a magnetic attraction force between the armature and a mover. A linear motor includes a first member and a second member. The first member is configured with at least a magnetic pole of a first polarity having a first opposed portion and a magnetic pole of a second polarity having a second opposed portion. The second member is held by the first opposed portion, while the second member is held by the second opposed portion and moves relatively. The first member is formed of an iron core and a winding, and the second member is formed of a permanent magnet, a magnetic material, a winding of a single type or a combination of a plurality of types of materials.

摘要： An electric vehicle torque controller has a torque calculating unit and an actuate torque detecting unit. The calculated torque signal is compared with the actual torque to generate a torque compensation value, which is converted to a torque current signal. The torque current signal is used to a slip frequency, which is added to the output of an angular speed detector and used to set a secondary magnetic flux value. A secondary magnetic flux signal is generated according to the secondary magnetic flux value and the torque current signal. A secondary magnetic flux estimating unit generates an estimated secondary magnetic flux value, which is used to determine the exciting current. Primary motor current is controlled in response to the exciting current, the torque current, motor speed and slip value.
