摘要： A motor is provided including a motor housing, an end cap secured to an open end of the motor housing, a stator, a rotor shaft, a rotor mounted on the rotor shaft; and a positional sensor circuit board including position sensors in magnetic interface with the rotor. The end cap includes a radial body having a center pocket arranged to securely support a bearing of the rotor shaft, and a molded structure formed through at least a portion of the radial body. The molded structure includes: a first portion formed to axially constrain the bearing within the center pocket on one side of the radial body, and a second portion forming a support structure projecting from another side of the radial body to structurally support the positional sensor circuit board relative to the rotor.

摘要： An electrical machine comprises a stator (101), a rotor (102), and bearings (103) configured to rotatably support the rotor with respect to the stator. The electrical machine comprises a force generating device (104) attached to the stator and comprising an actuator (105) for directing an axial force to an end of a shaft (106) of the rotor. The actuator can be hydraulically, pneumatically, or electrically driven. While the electrical machine is transported by using for example a trailer, truck, locomotive, or ship and transportation support is needed, the actuator is controlled to direct the axial force to the end of a shaft to remove clearances from the bearings and thereby to protect the bearings against damaging during the transportation. While the electrical machine is used for its purpose as a motor or generator, there is advantageously a physical air gap between the actuator and the end of the shaft.

摘要： A motor case part (30) having a stator (36) and a gear case part (50) having a reduction mechanism (SD) are integrally formed of the same material. In this manner, heat is directly dissipated from the motor case part (30) to the outside without the gear case part (30). Therefore, a brushless wiper motor (20) can be improved in heat radiation performance so as to enhance strength in high temperature can be realized. By manufacturing the motor case part (30) and the gear case part (50) from aluminum, while sufficient radiation performance is secured, a thickness thereof is made thin and lack in rigidity can be overcome. Furthermore, It is unnecessary to manufacture the motor case part (30) and the gear case part (50) individually and it is also unnecessary to perform pressing to a steel plate like the conventional art. Therefore, workability of the motor case part (30) and the gear case part (50) can be improved.

摘要： A motor includes a substantially cylindrical housing, a rotor assembly, a cover, and a cooling fan. The cooling fan is installed at one end of a rotating shaft of the rotor assembly to induce airflow. The cover, which is mounted to the housing, is provided with a plurality of wind-caching projections, each of which is located above one upstream through hole defined on the housing and faces towards the cooling fan. The wind-catching projections can receive the airflow induced by the cooling fan and guides the airflow to enter the housing via the upstream through holes to dissipate the heat accumulated in the motor, so that the motor can be prevented from damages due to heat accumulation. Therefore, the performance and service life of the motor can be increased.
