Working Principles

The EL7457CSZ-T7 is a brushless DC motor driver that utilizes pulse-width modulation (PWM) signals to control the speed and direction of the motor. It operates by receiving input signals from a microcontroller or other control circuitry and generates three-phase output signals to drive the motor coils. By adjusting the duty cycle of the PWM signals, the driver can regulate the motor's speed and torque.
