Common Problems of Micro Motors for Floor Sweepers

2025-07-31

Common problems of micro motors for floor sweepers:

What causes the slow rotation speed of the floor sweeper motor when starting?
If the rotation speed is only slow at startup and returns to normal after startup, it may be due to factors such as mismatched starting capacitors, the motor's design (based on site requirements), or excessive load resistance, which result in a too long starting time.
If the rotation speed remains slow after startup, the possible reasons may include insufficient voltage, mismatched capacitors, or high rotational resistance.
What should be noted when using a 60HZ floor sweeper motor on a 50HZ power supply?
Because the current frequency of the floor sweeper motor is lower than the designed frequency, the no-load back electromotive force generated during its rotation decreases, and the no-load current increases, which may damage the motor. Therefore, it is required to reduce the no-load voltage.
What impact does the number of poles of the floor sweeper motor have on its selection?
Currently, motors have 2/4/6/8 poles, and motors for special purposes may have more poles. The more poles a motor has, the lower its rotation speed, but the greater its torque. When selecting a floor sweeper motor, you need to consider the required starting torque of the load. For example, a load that starts with a load requires a greater torque than one that starts with no load. For high-power and heavy-load starting, you also need to consider reduced-voltage starting (or star-delta starting). Regarding the matching of the rotation speed between the motor (after determining the number of poles) and the load, you can consider using belt pulleys of different diameters for transmission or a variable-speed gear (reducer) for matching. If the power requirement of the load cannot be met through the belt or gear transmission after determining the number of poles of the motor, then you need to consider the power of the motor.
Improving the noise problem of floor sweepers
Using a brushed motor for the floor sweeper, the magnetic field generated by the magnets in the iron core structure of the brushed motor causes a cogging effect: when the magnetic field in the rotor cuts the stator teeth, magnetic force is generated. When the magnetic force moves from one tooth to another, it either assists or resists the rotation, causing the rotation to have regular acceleration or deceleration. The motor rotates stably, with stable speed ripple and torque ripple, low efficiency loss, small vibration, and low noise.
