Siemens AQ14002B Variable Speed AC Motor Drive

Siemens AQ14002B RELCON is a 2 HP variable-speed AC motor drive designed to provide adjustable speed control for small industrial motors. As part of Siemens’ RELCON AQ1400 family, this drive modulates motor speed by varying the output frequency and voltage delivered to an AC motor, enabling smooth acceleration and deceleration and precise speed regulation to match changing load conditions. This model targets compact installations and standard motor-control applications where simple, reliable speed control is required. The 2 HP rating communicates its power-handling capability for light- to medium-load operations, making it suitable for tasks that demand consistent torque at a set speed within automation environments. By enabling precise speed setpoints, the AQ14002B supports energy-efficient operation and improved control of mechanical loads, reducing vibration and wear compared with fixed-speed configurations. The AQ14002B variant reflects a specific option within the AQ1400 line, designed to integrate with typical industrial control schemes and Siemens’ broader ecosystem of automation components.
