Micromotor refers to a motor with a diameter smaller than that or a rated power smaller than that. Its market application fields are extremely wide, involving the national economy, national defense equipment, and all aspects of human life. Micromotors are precision machinery and therefore have higher requirements on their design. Specifically, it mainly includes the following aspects:
The motor must be able to work for a long time.
When the temperature is within the range of one degree Celsius (for different types of micromotors, the maximum temperature has different regulations, and the bottom wire is not higher than +), and when the temperature is within the range of 1°C, the motor must be normal work. In a medium with relative volatility of soil%, the motor must work normally at the temperature of the soil.
When the voltage and frequency of the power supply deviate from the fixed values as follows, the motor must work normally: the voltage of the auto-tuning machine is earth and the frequency is volts. The voltage of the servo motor powered by the power supply is : The voltage of a power supply with a voltage of 1 volt is the voltage of a power supply with a voltage of 1 volt.
Under the rated load, after a very long period of operation of the Hui motor, the temperature rise of the motor shall not exceed the following number (measured according to the resistance method): the motor operating in + medium is in a medium of 10°C Working motor
Under standard temperature and humidity, the resistance of the motor and all conductive parts to the case and to each other shall not be less than megohms. In Xun, where the relative undulation is ±0.0°C, the motor is removed after being shut down for day and night. The measured current limit of the mast rafter after 10 minutes is not less than 100 ohms under normal conditions. After 10°C minutes, The measured resistance should not be less than megohms.
At standard temperature and temperature, apply the working AC voltage to the motor for one minute, and all conductive parts and the casing must not be broken down.
Using noise measurement (objective method), the noise emitted by the automatic angle machine during operation shall not be greater than the requirements of the technical wood system.
Motors of the same model must be interchangeable.
The surface of the motor must have an anti-corrosion layer, and the windings must be impregnated with moisture-proof paint.
my country's micromotor production and supporting manufacturers are located at home, with more than 10,000 employees and a total industrial output value of more than 100 million yuan. The micromotor industry has become an indispensable basic product industry in the national economy and national defense modernization.
