The Working Principle of RM25030-3PR

RM25030-3PR adopts the advanced PWM control pulse width modulation mode, and the control pulse signal is generated by MCU pulse generator. Its output phase current and voltage can reach the value of 0- rated current and rated voltage at very low pressure when deviation is 0, and it can keep the target speed constant under rated load. The pulse width control model is adopted in the design of RM25030-3PR.

The pulse width modulation strategy adopted by RM25030-3PR motor drive can accurately control the output phase current of the motor and the power stage voltage. The output phase current of the motor can be an AC sine wave, and the output voltage can be any value within the switching frequency. The output phase current of the motor is proportional to the duty cycle of the pulse width signal, and the instantaneous peak current is limited by the voltage supply value of the switching transistor.

The pulse width modulation in RM25030-3PR is to regulate the rate of motor consumption of energy so as to drive the motor at a required speed. During the process, the control electronics converts the average current request into a duty cycle request signal. The duty cycle is high when the motor needs more current. The power conversion stage will output dedicated power pulses with corresponding duty cycle. These pulses drive the motor to generate torque, and its speed is determined by the frequency of pulses applied.

RM25030-3PR motor drive can accurately control the output phase current and voltage of the motor. At the same time, it also has the advantages of low current ripple, small step angle, wide speed range and high resolution. It can be effectively used in various industries and the application fields to achieve medium and low voltage application settings.
