reglermotor

Reglermotor is a term used to describe electric motors that include an integrated regulation subsystem to maintain a specified operating parameter, most commonly rotational speed or output torque. The defining feature is the presence of feedback and control circuitry within or closely coupled to the motor assembly, allowing automatic adjustment of excitation or drive signal in response to measurement of the parameter being controlled.

Typical reglermotor architecture comprises the motor itself, a sensor such as an encoder or tachometer, a power drive, and a control unit that runs a feedback algorithm (often a PID controller). The control loop compares a reference value to the measured value and generates a corrective command that reduces error. These devices can be based on direct current (DC) motors, alternating current (AC) motors, or brushless DC motors, with regulation implemented through electronic speed controllers or servo drivers.

Applications include industrial automation, robotics, conveyors, fans and blowers, and precision machines where stable speed or torque is essential. Reglermotor variants might offer functions such as speed ramping, torque limiting, position hold, or soft-start to protect mechanical systems.

Compared with open-loop motor drive systems, reglermotor arrangements provide higher accuracy and repeatability and can improve energy efficiency. Drawbacks include higher cost, more complex commissioning, and potential control instability if gains are not properly tuned or if sensors fail.

Terminology varies by region; the concept is often described in practice by terms such as servo motor, motor with closed-loop control, or regulated drive rather than a distinct standard product category. No single standard definition exists in general engineering literature.
