Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

The direct-current variable frequency motor shown in fig. 1-4 comprises a plastic shell 7, wherein an iron shell 3 is arranged in the plastic shell, a magnet ring 4 is arranged in the iron shell, a stator 5 is arranged in the magnet ring, a copper coil is arranged on the stator, the center of the iron shell is connected with a bearing rod 1, the bearing rod is connected with a ball bearing arranged on the plastic shell, a PCB adapter plate is further arranged in the plastic shell, and a variable frequency control module capable of controlling the rotating speed is further matched with the PCB adapter plate.

The magnet ring is respectively adsorbed and positioned with the stator and the iron shell, and the bearing rod is connected with the iron shell in a riveting manner. The bearing rod is also provided with an E-shaped clamping ring 2, and the E-shaped clamping ring is clamped into the groove of the bearing rod. The ball bearings include a small ball bearing 6 that is snapped into a ferrule in the plastic housing and a large ball bearing 10 that is snapped into a surface hole in the plastic housing. The stator is sleeved in the rubber shell and clamped tightly by the inner column. The bearing rod is also provided with a sound insulation cushion cover 11. The plastic shell is also provided with a line pressing plate 9. The PCB is clamped into a rubber shell groove of the plastic shell.

The direct current motor of the invention is a motor which converts direct current electric energy into mechanical energy and has good speed regulation performance. The PCB is communicated with a copper coil on the stator through soldering tin and is used as a conductor to be introduced with current, and then the current flows through the coil; according to the electromagnetic force law, the stator is used as a field coil to be electrified to generate a stator magnetic field, and the iron shell and the magnet coil which are electrified generate electric power in the stator magnetic field to form torque to push the iron shell to rotate; the bearing rod is driven by the rotation of the iron shell to conduct mechanical motion which is guided by the big/small ball bearings and does not deviate in the positive direction.

The motor can change the rotation direction of the inner rotor of the motor by changing the direction of the introduced current.
