Have you ever had any problems because of the unreasonable match between the inverter and the motor? For example, the phenomenon of burning machines, today, the Senli Motor editor will take you to a simple understanding of the problem of matching the motor and the inverter.

       We now use the production mechanical load can be roughly divided into constant power load, constant torque load and fan, pump, different load types of inverter requirements are different, we can be reasonably prepared according to the situation. For example, the torque required by the paper machine, the coiler and the uncoiler in the plastic film production line in the moment motor use scenario is roughly inversely proportional to the speed, and belongs to the constant power load.

       The constant power nature of the load should be in terms of a certain range of speed variations. When the speed is very low, it is restricted by mechanical strength and will change to constant torque load at low speed. When the motor adjusts the speed with constant flux, it adjusts the speed with constant torque. In the weak magnetic speed regulation is constant power speed regulation.

       Constant torque load at any speed,TLAlways remain constant or almost constant. When the frequency converter drives a load of constant torque nature, the torque at low speed should be large enough and there is sufficient overload capacity. If you need to run at a steady speed at low speed, then you should consider the heat dissipation performance of the motor to avoid the motor burning due to high temperature rise.
