Drive systems are assemblies that deliver controlled motion and power from a prime mover (motor or engine) to a machine or load. They combine mechanical, electrical and control elements to regulate speed, torque, position and direction—making them fundamental to automation, transport, energy and industrial machinery.

Core components

• Prime mover: electric motor (AC, DC, servo, stepper), hydraulic motor, or pneumatic actuator.

• Power electronics / controllers: inverters, variable frequency drives (VFDs), servo drives or motor controllers that regulate speed/torque.

• Mechanical transmission: gearboxes, belts, chains, couplings, shafts and reduction units that match motor output to load requirements.

• Feedback & sensors: encoders, resolvers, tachometers and torque sensors for closed-loop control.

• Software & control logic: motion controllers, PLCs, and embedded firmware that implement trajectories, safety limits and diagnostics.

• Auxiliary systems: brakes, cooling, filters, cable management and safety interlocks.

Major types of drive systems

• Electric drives: the most common—use AC induction, synchronous, permanent-magnet or DC motors plus power electronics for precise control.

• Servo drives: high-precision systems for position and speed control in robotics, CNC machines and pick-and-place equipment.

• Stepper motor drives: open-loop or microstepping drives for simple position control at modest speeds.

• Variable speed drives (VFDs): control AC motor speed by varying frequency/voltage for pumps, fans and conveyors.

• Hydraulic drives: provide very high force/torque for heavy equipment (excavators, presses) with excellent overload capability.

• Pneumatic drives: simple, fast actuation for light industrial tasks and packaging machines.

• Integrated/compact drives: motor + gearbox + electronics in a single package for compactness and simplified installation.
