Electric Water Pump |
| 摘要 |
Provided is a highly reliable and compact electric water pump. A motor unit includes an axial gap motor having a stator and rotors. A partition formed with a nonmagnetic member is interposed between the motor unit and a pump unit. A torque generated by the motor unit is transmitted to the pump unit by a contactless magnetic coupling in an axial direction. The partition is formed to have a bottomed cylindrical shape. The motor unit and pump unit are provided with driving magnets and passive magnets respectively which are opposed to each other with a cylindrical part of the partition between them. |
