Sealing machine price and the choice of motor relationship

The following to see the sealing machine price and the choice of the motor relationship.

In the relation between the sealing machine price and the choice of the motor, the motor should be checked according to the starting conditions. Synchronous motors should also be retracted into the loading moment inspection.

In the relation between the price of sealing machine and the choice of motor, the machine with continuous working mode of load change should be selected according to the equal moment method of equal generation and checked according to the permissible overload torque.

In the relation between the price of sealing machine and the choice of motor, the rated power of the machine with intermittent working mode should be selected according to the power of equivalent load of typical period converted to standard load continuity rate, and checked according to the allowable overload torque.

In the relation between sealing machine price and motor selection, short-time quota motor should be selected for short-time working machinery, and intermittent quota motor can also be selected according to allowable overload torque. For the intermittent working mode of machinery, when the load characteristic rate is more than 60%, should choose continuous rating motor.

In the relation between the sealing machine price and the choice of the motor, the temperature of the medium at the place where the motor is used shall meet the requirements of the motor's technical conditions (insulation level). When the altitude and temperature of the medium at the place where the motor is used do not conform to the requirements of the working conditions, the power of the motor shall be calibrated according to the requirements of the technical conditions.

In the relationship between the price of sealing machine and the choice of motor, the choice of rated power of motor should be based on the type of machine and its importance, there should be an appropriate reserve coefficient (overload coefficient).

For power calculation methods, please refer to the motor and drag or mechanical design monographs, which are beyond the scope of this book.

The rated speed, installation structure and speed regulation method of the motor should be suitable for the production plant and its process program.

In the relation between the sealing machine price and the choice of the motor, the choice of the motor type is as follows:

(1) If there is no special requirement for starting, regulating speed and braking, cage motor should be used, but for motors with long time operation and large power, synchronous motor should be generally used. When only a variety of speeds are required, multi-speed cage motors should be used in general.

(2) the quality requirements of speed regulation is not high, and speed regulation ratio is not big, or according to the starting conditions using cage motor unreasonable, generally should be used winding rotor motor.

If there are higher requirements for starting, speed regulating and braking, the type of motor should be selected according to the requirements of production process. Such as dc motor, electromagnetic speed motor or variable frequency starting equipment.

The rated voltage of the motor shall be determined by the comprehensive consideration of distribution voltage, distribution mode and rated power of the motor. Under the condition that the power capacity of the low-voltage motor is allowed, the power of the low-voltage motor should not be more than 300W, and the high-voltage motor should be used if it is more than 215kW.

I hope the above information on the relationship between sealer price and motor selection is helpful to you.
