摘要： The invention relating to a stator assembly (1) in an electrically multi-phase activated drive motor with a stator (3) comprising several stator teeth (2), wherein the stator teeth (2) comprise a tooth surface (5) directed toward a pivotably supported rotor (4), has as its objective specifying a stator assembly [1] that enables a reduction of the noise and vibrations occurring during operation of a drive motor. This task is resolved thereby that at least one stator tooth (2) for each motor phase of the drive motor is implemented such that on the tooth surface (5) of this stator tooth (2) are disposed at least one first planar-formed surface region (6) and maximally one second surface region (7) comprising a curvature.

摘要： My invention shows how to get increased torque and efficiency in an electric car. By combining the use of an electric motor and an electromagnet focused on a cog of north and south poled magnets the increased strength of the electromagnet could be used to provide greater torque to an electric car. Furthermore the arrangement of motor and electromagnet could be used to provide greater efficiency of the engine. By using only a small amount of battery power to slightly turn the motor the bulk of the force used to propel the car could come from the electromagnet. The loads on the respective batteries could be maximized.

摘要： An electric machine comprise a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles, the second carrier being arranged to move relative to the first carrier. An airgap is provided between the first carrier and the second carrier. The electromagnetic elements of the first carrier include posts, with slots between the posts, one or more electric conductors in each slot, the posts of the first carrier having a post height in mm. The first carrier and the second carrier together define a size of the electric machine. The magnetic poles having a pole pitch in mm. The size of the motor, pole pitch and post height are selected to fall within a region in a space defined by size, pole pitch and post height that provides a benefit in terms of force or torque per weight per excitation level.

摘要： A stator is provided. The stator includes a yoke part of an annular shape, tooth winding portions that protrude inward from the yoke part and around which an electric wire is wound, and a tooth end portion formed on an inward side of the tooth winding portion. The stator is formed by stacking steel plates in a direction corresponding to a rotational axis of a motor. The tooth winding portion is formed by stacking the steel plates having different shapes such that at an end portion in the stacking direction, thickness of the tooth winding portions gradually decrease toward the end portion in the stacking direction, and the yoke part and the tooth end portion include protruding portions formed by stacking the steel plates, such that the protruding portions protrude from the tooth winding portion in the stacking direction.
