Characteristics, features, and performance comparison of small motors
When designing equipment that uses motors, it is necessary to choose the motor that is most suitable for the desired operation.
We have previously introduced the characteristics and driving methods of brushed motors, stepper motors, and brushless motors. Here, we will compare their features, performance, and characteristics,
hoping to be a reference for you when choosing motors. However, as there are multiple specifications included in the same category of motors, please use it only as a reference.
Ultimately, detailed information needs to be confirmed through the technical specifications of each motor.
Characteristics of small motors
The following table summarizes the characteristics of stepper motors, brushed motors, and brushless motors.
Stepper motor, brushed motor, brushless motor
The rotation method excites the armature winding in the order of determining each phase (two, three, five phases) through the driving circuit, and switches the armature current through the
sliding contact rectifier mechanism of the brush and commutator. By replacing the functions of brushes and commutators with magnetic pole position sensors
and semiconductor switches, brushless technology can be achieved
Is the driving circuit necessary or not
The torque is relatively large. The starting torque is large, especially at low speeds, and the torque is proportional to the armature current (the torque is relatively
large at medium to high speeds)
The rotational speed is directly proportional to the input pulse frequency. The out of step region in the low-speed range is proportional to the voltage
applied to the armature. The speed decreases with the increase of load torque
High speed rotation is difficult due to the limitations of the electric brush and commutator rectifier mechanism, and can reach up to several thousand rpm
or several thousand to tens of thousands of rpm
The rotational life is determined by the bearing life. Tens of thousands of hours are limited by the wear of electric brushes and commutators, and hundreds
to thousands of hours are determined by the bearing life
The forward and reverse rotation methods require changing the order of excitation phases in the drive circuit to reverse the polarity of the pin voltage.
Reverse rotation requires changing the order of excitation phases in the drive circuit
Controllability can be achieved by open-loop control with rotation speed and position (rotation amount) determined by command pulses (but there is a problem of step loss). Constant
speed rotation requires speed control (feedback control using speed sensors). Since torque is proportional to current, torque control is easy to achieve
Easy to obtain: there are many varieties, easy to obtain: there are many manufacturers and varieties, and many options. Difficulty: Mainly specialized motors for specific applications
If the price includes the drive circuit, the price is relatively cheaper than brushless motors, while coreless motors are a bit expensive due to their upgraded
magnets. If the drive circuit is included, the price is more expensive

Speed torque characteristics of small motors
The following summarizes the speed torque characteristics of various small motors. It can be considered that brushless motors and brushed motors are basically the same.
key points
The characteristics, performance, and comparative results of small motors can be used as a reference for motor selection.
The same category of motors includes multiple specifications, so the characteristics, performance, and comparison results of small motors are only for reference.
Ultimately, detailed information needs to be confirmed through the technical specifications of each motor.
