Baldor Electric Company VS1GV25-1B Variable Frequency Drive

The Baldor VS1GV25-1B is a 5 HP closed‑loop vector drive designed for precise, adjustable speed control of 230/240 VAC three‑phase motors in industrial and OEM settings. This 240 VAC, 3‑phase input unit from Baldor’s VS1GV line delivers true vector performance with closed‑loop control for improved torque and speed regulation at low RPMs, and it uses a high‑frequency PWM switching scheme up to 8 kHz to balance performance and EMI considerations. The model VS1GV25‑1B is offered in frame sizes AA, 4B, and 5B and includes a frame brake on this model number, making it suitable for applications requiring braking capability. Typical input current is around 15.2 A at 240 V, with a nominal 3.7 kW (5 HP) motor output, aligning with Baldor’s H2 technology platform in the VS1 family. The drive is part of Baldor’s legacy of motor controls now under ABB Baldor Reliance, and it is designed to provide stable speed control and torque management for 3‑phase motors in a wide range of industrial tasks. With its vector control capability, the VS1GV25‑1B aims to deliver reliable performance across a broad speed range and is compatible with standard 3‑phase motors, enabling upgrades to variable speed without changing the motor.
