How To Test The Speed Of A Brushed DC Motor?

The speed of a DC brushed motor can be tested by using some tools and equipment. The following are some methods to test the speed of DC brushed motors:

1. Using a multimeter: You can use the speed measurement function of a multimeter to test the speed of a motor. Ground the black test pin of the multimeter, connect the red test pin to one lead of the motor, then turn the motor and observe the reading of the multimeter to get the speed of the motor.

2. Use Hall sensor: Hall sensor can measure the position and speed of the motor rotor. Install the Hall sensor on the rotor of the motor, then connect the output signal of the sensor to a digital measuring instrument to measure the rotational speed of the motor.
3. Using a tachometer: A tachometer is a device specifically designed to measure the rotational speed of a rotating object and can be used to test the rotational speed of a DC brush motor. The speed of the motor can be measured by contacting the sensor of the tachometer with the rotating object on the motor shaft and then starting the motor.

4. Use photoelectric measuring instrument: Photoelectric measuring instrument is a device used to measure the speed of object movement, which can be used to test the speed of DC brush motor. The speed of the motor can be measured by aligning the sensor of the photoelectric meter with the object on which the motor is rotating and then starting the motor.

These are some common ways to test the speed of DC brushed motors. It is important to note that when performing the speed test, you need to comply with the relevant safety regulations to ensure that the testing process is safe and reliable.
