2. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

3. Direct torque control - Wikipedia

   en.wikipedia.org/wiki/Direct_torque_control

   Direct torque control (DTC) is one method used in variable-frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors.This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor.

4. Vector control (motor) - Wikipedia

   en.wikipedia.org/wiki/Vector_control_(motor)

   Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector.

   In 2011, Baldor was acquired by ABB Ltd of Switzerland in an all-cash deal of US$4.2 billion ($1.1 billion debt included). The company continued to operate as Baldor Electric Company A Member of the ABB Group. On March 1, 2018, Baldor Electric Company's name was dissolved into the ABB brand, becoming ABB across all of its locations.

6. Motor drive - Wikipedia

   en.wikipedia.org/wiki/Motor_drive

   A variable frequency drive (VFD) or variable speed drive (VSD) describes the electronic portion of the system that controls the speed of the motor. More generally, the term drive, describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products.
