Three principles for the selection of cheap silent dc motor
Micromotor is a motor with a small volume and capacity, and an output power of several hundred watts or less. The motor and its use, performance, and environmental conditions require special motor. The full name micro-special motor, referred to as micro-motor. It is commonly used in control systems to achieve the functions of detection, calculation, amplification, execution, or conversion of electromechanical signals or energy, or to drive mechanical loads. It can also be used as an AC and DC power source for equipment.
Three principles for the selection of micro-motors:
1, reasonable choice of micro-motor power
The maximum power output of the motor is limited. If the power selection of the motor is too small, the load exceeds the rated output power of the motor and the motor overload occurs. When the overload occurs, the motor heating, vibration, speed drop, and sound anomaly occur. When it is seriously overloaded, it will burn the motor. Too much power will cause economic waste. Therefore, it is very important to choose the power of the motor reasonably.
2, according to the need to reasonably choose micro-motor specifications
In the case where the power supply voltage is adjustable, the specifications of torque, speed and product's corresponding rating can be selected according to actual needs, and the required speed can be obtained by changing the voltage; When the power supply voltage is fixed, if there is no suitable specification product available, the appropriate specification can be selected according to the torque, and the voltage and speed of the product can be adjusted appropriately.
3, type selection
Preference should be given to the use of ferrite permanent magnet micromotors with high efficiency, low price and low temperature rise. Only when the performance requirements are strict, the volume is small, and the ambient temperature is high, aluminum nickel cobalt permanent magnet micromotor or rare earth permanent magnet micromotor is considered.
Micro motors are widely used in various portable electronic devices or appliances, such as tape recorders, VCD players, record players, electric massagers and various toys. They are also widely used in automobiles, motorcycles, electric bicycles, battery vehicles, ships, aviation, and machinery. And other industries, It is also widely used in some high-precision products. So we have to follow the rules when choosing.
