Unidrive AC Variable Speed Drive – Control Techniques UNI1401
The UNI1401 is an AC variable speed drive (“AC Variable Speed Drive”) from the Unidrive Classic series by Control Techniques. Designed to control three-phase asynchronous motors, the drive supports both open-loop (V/f) and closed-loop field-oriented control (flux vector), with a three-phase 380–480 V AC input and a rated power of approximately 1.5 kW. The unit supports encoder feedback for high-precision speed and torque applications.
The Unidrive drive controls the speed and torque of the AC motor by modulating the output voltage and frequency using PWM technique: it provides smooth starts, controlled regenerative braking, and speed stability under varying loads. In case of failure, the driven axis or spindle loses complete control, rendering the machine inoperable until the drive is replaced or repaired.
Control Techniques is a British manufacturer founded in 1968, specialised in variable speed drives and servo drives for industrial automation. Acquired by Emerson Electric in 1994 and later by Nidec Corporation in 2017, it now operates as Nidec Industrial Solutions. The Unidrive Classic series is legacy / discontinued, superseded by the Unidrive SP and Unidrive M generations.
