M-797 is a motor operating instrument that measures electrical reactance, phase shift, and resistance. Its main application field is low-voltage motors in the industrial sector. It is used to measure the performance of motors and generate signals to control their behavior. The working principle of the M-797 is based on the reactance-adjustable controller (RAC) concept.

The motor-operating instrument consists of two parts, the reactance-adjustable controller (RAC) and the motor control unit (MCU). The RAC is the primary component of the instrument, which contains two major components, the electrically variable reactance (EVR) and the feedback transducer (FT). The EVR is a reactive element, typically a non-inductive resistor, whose resistance can be adjusted remotely. The FT is a transducer for measuring the electrical reactance of the EVR. The MCU is the main driver of both the RAC and the motor. It contains a motor driver, controller, and a microprocessor for controlling the working states of the motor. The motor can be operated in either the phase-control-arm or the voltage-control-arm mode. Depending on the desired behavior, the MCU configures the RAC to enable the desired mode of operation.

The working principle of the M-797 consists of two main operations. The motor-operating instrument uses the EVR and FT to measure the electrical reactance of the motor. This is done by adjusting the resistance of the EVR according to the motor\'s actual current and voltage levels. After the resistance of the EVR is adjusted, the MCU measures the reactance of the EVR and its corresponding motor\'s resistance. The MCU then sends a signal to the motor driver, which adjusts the motor’s speed, torque, and power accordingly. This ensures that the motor runs at the desired level of efficiency.

The M-797 has various applications, including diagnostics of motor control systems, testing of electrical drives and induction motors, and determining the performance of electric motors. It is also used to control the dynamic behavior of motors when they work in different environmental conditions. The M-797 also offers protection for motor systems against over-current and over-voltage faults. It is used in many industries, including automotive, food and beverage, and industrial automation.

M-797 is a useful and reliable motor operating instrument. It is easy to use and offers accurate measurements and precise motor control. It is suitable for low-voltage motors in industrial applications and provides a cost-effective solution for controlling and monitoring motor performance. With high accuracy and reliable performance, the M-797 is an effective tool for measuring and controlling the performance of motors.
