    • A brushless permanent magnet electric machine with a fixed radial air gap is operated to a much higher speed than normal maximum speed by the reduction in effective magnet pole strength. Increasing the amount of axial misalignment of the permanent magnet rotor and constant velocity bearing proportionally increases the speed and reduces the torque. The permanent magnet rotor is offset axially to provide axial misalignment between the rotor magnet poles and the stator, reducing the effective magnet pole strength or flux to the stator. An integral constant velocity linear bearing is used to couple the movable rotor and the fixed position motor shaft. A thrust bearing is actuated to offset the magnetic rotor against the attractive magnetic forces toward the stator. The use of a constant velocity linear bearing allows the motor shaft, radial support bearings, position encoder, cooling fan, and output coupling to remain in a constant position while rotor position is offset.
    • 具有固定的径向气隙的无刷永磁电机通过有效磁极强度的降低而以比正常最大速度高的速度运行。 增加永磁转子和恒速轴承的轴向未对准量成比例地增加速度并降低转矩。 永久磁铁转子轴向偏移以提供转子磁极和定子之间的轴向不对准,从而降低有效磁极强度或通向定子的通量。 一个整体的等速线性轴承用于连接可动转子和固定位置电机轴。 推力轴承被致动以抵靠磁性转子抵抗朝向定子的有吸引力的磁力。 使用恒速线性轴承允许电机轴,径向支撑轴承,位置编码器,冷却风扇和输出联轴器在转子位置偏移时保持恒定位置。

    • The invention relates to an electric motor with electromagnetic brake which is used notably for an angle grinder and comprises a stator (11) having at least one pole pair. The at least one first pole (14) has a pole shoe (15) facing inwards towards the rotor circumference and is surrounded by a stator winding (20). Said pole (14) houses a brake device (22) which serves to brake a rotor (12) and comprises a brake element (23) which via the magnetic field of the stator winding (20) can be adjusted against a brake force (33). According to the invention the brake element (23) is configured as a rocker which is eccentrically subjected to the brake force (33). Owing to the eccentric force application the brake element (23) can be arranged with a release arm (30) in the magnetic flux of the stator winding (20) in such a way that a high release torque can be obtained.
