Key points for selecting small three-phase asynchronous motors
1. Rongcheng Motor selects the appropriate type of motor based on the mechanical load nature and production process, as well as the requirements for starting, braking, reversing, and speed regulation of the motor.
2. Based on the requirements of load torque, speed variation range, and starting frequency, considering the temperature rise limit, overload capacity, and starting torque of the motor, the power of the motor should be reasonably selected to ensure a reasonable power matching, striving for safety, reliability, and economy.
3. Rongcheng Motor selects the protective structure type of the motor based on the environmental conditions of the place of use, such as temperature, humidity, dust, rainwater, gas, corrosion, and flammable and explosive gas content, and considers necessary protection methods.
4. Determine the voltage level of the electric motor according to the voltage standards of the enterprise power grid and the requirements for power factor.
5. Rongcheng Motor selects the rated speed of the electric cargo motor based on the maximum speed of the production machinery, the requirements for the electric transmission speed control system, and the complexity of the mechanical deceleration.
6. When choosing a motor, one should consider the price, construction cost, and operating cost of the product, striving for the best comprehensive economic benefits. In dry and clean places, it is recommended to use Y series motors with "IP23" as much as possible, because the price of this type of motor is about 70% of that of Y series motors with the same capacity as "IP44", and the manufacturer can save materials; For continuous operation and high load rates, YX series high-efficiency motors should be used to save energy and improve overall economic benefits.
7. When choosing a motor, factors that affect installation, operation, and maintenance should be considered, striving for easy installation and maintenance, and reliable operation.
8. To implement the country's technological and economic policies, actively adopt new products promoted by the state, and avoid outdated products.
