AC-to-AC converter

A solid-state AC-to-AC converter converts an AC waveform to another AC waveform, where the output voltage and frequency can be set arbitrarily.

See Motor drive and AC-to-AC converter

The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power.

See Motor drive and Affinity laws

Axial piston pump

An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block.

Beier variable-ratio gear

The Beier variable-ratio gear or Beier variator is a mechanical drive offering a continuously variable gear ratio between input and output. Motor drive and Beier variable-ratio gear are variators.

Clutch

A clutch is a mechanical device that allows the output shaft to be disconnected from the rotating input shaft.

Continuously variable transmission

A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios.

Control theory

Control theory is a field of control engineering and applied mathematics that deals with the control of dynamical systems in engineered processes and machines.

Eddy current

In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.

Gray code

The reflected binary code (RBC), also known as reflected binary (RB) or Gray code after Frank Gray, is an ordering of the binary numeral system such that two successive values differ in only one bit (binary digit).

Hall effect

The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.

Utility frequency

The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
