The agitator shaft is usually driven by an electric motor. As the speed of stirring equipment is generally low, so the motor is mostly
In many cases, it is combined with the transmission, and sometimes the frequency converter is used for direct speed regulation. To this end, when choosing a motor, special consideration should be given to the matching problem with the transmission. In many occasions, the motor and transmission together with the supply, design can be selected according to the transmission of the matching motor. 1 The basic principle of motor selection usually should be based on the stirring shaft power and stirring equipment around the working environment and other factors to choose the motor model, and follow the following basic principles: (1) according to the load nature of the stirring equipment and process conditions of the motor starting, braking operation, speed regulation, etc., choose the motor type.
② According to the requirements of load torque, speed variation range and starting frequency, considering the temperature rise of the motor to limit the starting torque of overload capacity, reasonable selection of motor capacity, and determine the cooling ventilation mode. At the same time, the selected motor model and rated power should meet the requirements of increasing the starting power when the stirring equipment starts.
