The system power is equal to the product of the inverter power and the motor power, as long as both are operating at a higher power, the system power is higher. From the power point of view, when selecting the power of the inverter, the following points should be noted:
1) The power value of the inverter is the most suitable for the power value of the motor, so that the inverter can work under high power value.
2) If the power classification of the inverter is not in step with the power classification of the motor, the power of the inverter should be as close to the power of the motor as possible, but it should be slightly greater than the power of the motor.
3) When the motor is frequently started and braked or is in heavy load starting and frequent operation, a larger inverter can be selected to use the inverter for long-term and safe operation.
4) After testing, the actual power of the motor is indeed sufficient, and the inverter with a power less than the power of the motor can be considered, but it is necessary to pay attention to whether the instantaneous peak current will cause overcurrent protection action.
5) When the power of the inverter and the motor are not together, the setting of the energy-saving program must be adjusted accordingly to achieve a higher energy-saving effect.

How Schneider contactors work
How it works
Contactor refers to an electrical appliance that uses a coil to flow through an electric current to generate a magnetic field, so that the contact is closed, and then the load can be controlled. Because it can quickly block the main circuit and frequently connect with the equipment of the high-current control circuit, it has been used in electrical engineering.

Schneider inverter motor control mode
Fundamentals of magnetic flux vector manipulation
The control of a three-phase asynchronous motor is much more messy than that of a DC motor because the current, voltage, induced potential, magnetic flux, etc., of the stator and rotor are all alternating.
However, the stator winding of the three-phase asynchronous motor is a symmetrical three-phase winding, which exerts a ...

Is there a restriction on the installation direction when Schneider installs the inverter?
It should be basically stored in the plate, the problem is that the plate with a fully enclosed structure is large, takes up a lot of space, and the cost is relatively high. This can be done by:
(1) The planning of the disc should be based on the heat dissipation required by the actual device;
(2) Profit ...
