AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.
Gearboxes and gearheads are speed reducers that consist of a set of gears, shafts, and bearings in an enclosed housing. In converting inputs to outputs, they reduce RPM and increase torque.
Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer.
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.
Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters.
Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy.
