The PVS-R-20 is the latest in a series of advanced variable speed, single-phase AC permanent magnet synchronous motor torque controllers. This type of torque controller is designed to enable precise and reliable speed control with minimum power consumption. It is suitable for a variety of applications including pumps, electric vehicles, laboratory and medical equipment, and more. The PVS-R-20 provides superb control characteristics andeasy wiring of the motor and control unit.

The PVS-R-20 features a unique system of robust input protection that ensures safe operation and prevents potential problems due to external interference or overloads. This advanced system is designed to provide maximum protection from voltage sags, short-circuits, and over-voltage. Additionally, the PVS-R-20 includes an efficient line filter that suppresses noise and interference from other electrical sources.

A sophisticated software package is available for the PVS-R-20, allowing for easy customization and setup. The software can be programmed to provide various speed profiles and acceleration/deceleration timing, in addition to external parameter adjustments for the current, voltage, phase shift, and other factors. The PVS-R-20 can also be operated manually, allowing the user to adjust the speed, direction, and frequency of the motor. The controller features several sensor inputs for speed and torque measurement.

The PVS-R-20\'s variable speed operation makes it ideal for applications such as air handling units or compressed air systems, where accurate flow and pressure regulation are required. It can also be used in medical applications where speed must be precisely controlled for a variety of procedures. The PVS-R-20 is also suitable for swimming pool pumps, industrial motors, and CNC machining centers.

The working principle of the PVS-R-20 is based on the use of pulse width modulation (PWM) for speed control. PWM works by varying the amount of power supplied to the motor by switching the voltage on and off, or pulsing, for a specific time period. By using a combination of frequency and voltage, the controller can precisely control the speed of the motor.

The PVS-R-20 also features advanced protection against overloads, short-circuits, and other dangerous conditions. This feature helps to ensure safe operation and prevents potential problems while providing maximum protection for the motor and control system.
