Motors & Motion
Motor drivers and motion-control components convert electrical energy into controlled mechanical motion. They form the motion backbone of robotics and automation.

DC motor drivers (H-bridge), stepper drivers, servo and BLDC controllers are the main types. Motor type, voltage/current rating, control method (PWM, step/dir) and protection features matter when choosing one. Robots, CNC, 3D printers and conveyors are the most common applications.

Frequently asked questions
What is an H-bridge?+
An H-bridge is a driver circuit that feeds current to a DC motor in both directions, enabling forward-reverse rotation and speed control. L298N and DRV8833 are popular examples.
What is the difference between a stepper and a servo motor?+
A stepper positions precisely step by step without feedback; a servo uses feedback (encoder) for very precise, fast position/torque control. Steppers are common in CNC, servos in robotics.
What should I watch when choosing a motor driver?+
The motor's voltage and peak current must not exceed the driver's ratings. Heat dissipation, overcurrent/temperature protection and control-interface (PWM or step/dir) compatibility also matter.
