Induction motors draw high starting current because the minimal rotor field at startup causes high impedance and lagging flux, combined with the need for high starting torque. This causes much higher current flow during startup compared to normal operation.
The process of connecting the gear to the motor shaft involves precise alignment, securing and torqueing to ensure optimal functionality.
Servo motors enable precise movements in robotics. To achieve a 90-degree rotation, understand servo basics, calculate pulse width, and control the motor with PWM signals.
