Ac motor test power supply solution

An AC motor is a device that converts electrical energy from alternating current into mechanical energy, mainly consisting of an electromagnet winding or distributed stator winding used to generate a magnetic field and a rotating armature or rotor. Because of its simple structure, high working efficiency, convenient manufacturing and other advantages, it is widely used in industrial and agricultural production, transportation, commerce and household appliances.

During the test of AC motor, it is usually not possible to directly start it to the maximum power, especially if the motor is not configured with speed regulation function. When the motor starts directly at full power, too high starting current will be generated, which will cause the output voltage of the power supply device to drop and fluctuate or trigger overcurrent protection, resulting in failure to start normally. By slowly increasing the working voltage of the motor, the speed gradually reaches the expected set value, which is also commonly known as the soft start of the motor, significantly reducing the starting current of the motor to ensure the normal development of the test. ZLG-PSA6000 series programmable AC power supply provides AC motor with convenient operation and accurate power supply test power supply solution, that is, LIST/STEP programming and adjustment of output voltage change rate and other two solutions, to achieve AC motor power supply slowly.

First, LIST/STEP programming scheme

The PSA6000 series programmable AC power supply STEP/LIST function allows the flexibility to set the starting voltage value, the end voltage value, the voltage step value and the voltage duration of each step, etc., to achieve the voltage from low to high step increase.

Second, adjust the rate of change of output voltage

The PSA6000 series programmable AC power supply allows the rate of voltage change to be set. By changing the rate of voltage change, the input voltage at both ends of the AC motor is linearly increased from low to high.

The voltage is output at a rate of change

ZLG PSA6000 series high-performance programmable AC power supply is a power grid analog output device with high precision and wide output range, the output power is 2~21kVA, the output frequency is more than 5000Hz, support output self-calibration can significantly improve the output accuracy, integrate rich cutting-edge application solutions, It provides normal or abnormal power supply conditions for electronic product performance testing and quality verification, and is equipped with perfect protection functions (OVP/OCP/OPP/OTP, etc.), which can easily cope with complex tests in the development, certification, production and other stages of AC motor.
