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.
Enclosure air conditioners remove the heat generated by electronic devices from the inside of cabinets or enclosures. They typically use refrigerants and include thermostatic controls to maintain programmed environmental conditions.
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.
