    摘要： A motor control device controls a driving of a motor having a motor winding. The motor control device includes a motor control unit and a parameter setting unit. The motor control unit controls the driving of the motor. The parameter setting unit sets a control parameter related to a driving control of the motor such that at least one of a motor torque and a motor speed is variable according to a system temperature.

    摘要： A stator assembly (10) for an axial flux motor (100) with a rotation axis (100a). The stator assembly (10) has a stator receptacle portion (30) of a motor housing (20) of the axial flux motor (100), a stator (40) and a potting body (50). The stator receptacle portion (30) defines a disk-shaped contact face (32a) for receiving the stator. The stator (40) is disposed on the disk-shaped contact face (32a). The stator (40) is potted in the stator receptacle portion (30). The potting body (50) is connected to the stator receptacle portion (30) in a form-fitting manner in such a way that the stator (40) in the stator receptacle portion (30) is secured by the potting body (50) at least in the axial direction (2).

    摘要： A drive motor for a suction device (400) or a machine tool in the form of a hand-held power tool (200, 300) or a semi-stationary machine tool. The drive motor (20, 120) has a stator (80) with an excitation coil assembly (86) and a rotor (40, 140) with a motor shaft (30, 130) which is rotatably mounted about a rotational axis (D) on the stator or relative to the stator (80) by means of a bearing assembly (24A) and which passes through a shaft through-opening (42, 142) of a laminated core (41, 141) held on the motor shaft (30, 130). The rotor (40, 140) has a magnet assembly (50) with at least one permanent magnet such that the rotor (40, 140) can be rotated about the rotational axis (D) by energizing the excitation coil assembly (86). The laminated core (41, 141) has at least one balancing section (55) produced by removing material from or notching the laminated core (41, 141), and/or the at least one permanent magnet is formed by a magnet body (52) which is magnetized when arranged on the laminated core (41, 141).

    摘要： A motor includes: a stator including a stator core and stator wiring; and a rotor. The stator core includes a teeth core and a yoke core. The teeth core includes: an inner cylindrical portion; and a plurality of teeth, each of which includes a body portion protruding outward from the inner cylindrical portion along a radius of the inner cylindrical portion. The yoke core has a cylindrical shape and is mounted onto the plurality of teeth to surround the plurality of teeth. The stator wiring includes: a coil wire wound around the body portion; and transition wiring electrically connecting together a plurality of the coil wires respectively wound around a plurality of the body portions. The transition wiring is provided in a region located inside the body portion along a radius of the body portion.

    摘要： A fitness device includes two support frames mounted in a box, two driving motors mounted on the two support frames, a pull rope reel connected to the driving motors, a fitness pull rope wound around the pull rope reel and extending out of the box, and a control system for controlling the driving motors. The control system includes a main controller, a power module, a communication module connected to the main controller, a driving circuit and a sampling module electrically connected to the driving motors and the main controller. The power module is electrically connected to the main controller and the communication module. The driving circuit is electrically connected to the power module, the main controller and the driving motors. The two symmetrical driving motors are used to drive the pull rope reel to drive the fitness pull rope, such that shakes and vibrations generated during exercise can be offset.
