LOW-VOLTAGE DIRECT CURRENT MOTOR |
| 摘要 |
A low-voltage direct current motor has a stator and a rotor rotatable relative to the stator. The rotor includes a rotary shaft, a rotor core fixed to the shaft, a commutator fixed to the shaft adjacent to the rotor core, and rotor windings wound about poles of the rotor core and electrically connected to the commutator. The stator includes a round housing, a permanent magnet mounted to an inner surface of the housing, and brushes disposed in sliding contact with the commutator. An input voltage of the motor is in the range of 7 to 36V, and a ratio of an outer diameter of the rotor core to an outer diameter of the housing is in the range of 67% to 75%. |
