DC gear motor factory accompanying the steady development of the automation industry, more and more products need to use gear motor, such as automatic conveyor belts, electric seats, and upgrades. But when the model is different, how to quickly and accurately choose a slowdroid motor for its own product. What is the phenomenon that the drive motor is not good? First, the motor power selection is unreasonable:
1. If the motor is selected too small. There will be a "small horse big car" phenomenon, causing long-term overload of the motor. It is damaged due to fever. Even the electric motor was burned.
2. If the motor power is elected. There will be a "big horse trainer" phenomenon. Its output mechanical power cannot be fully utilized, and the power factor and efficiency are not high (see table), which is not only unfavorable to users and grids. And it will also cause waste of electric energy.
Second, motor drive power calculation formula:
Motor power = torque × Motor input revolules × Efficiency / 9549 power calculation formula is P = TNη / 9549 When the motor is selected, first determine the speed of the motor you want, and then in the formula P is the rated motor (output) ) The power unit is kW-N is the rated speed N unit is the motor of a motor of 1440 to 2P, which is a motor. Take 0.8
