The B7A-R6B36 is a type of electric control device that is most commonly used in industrial applications. It is intended for speed control operations of 3-phase induction motors and can be used in the fields of oil, paper, chemical and many other manufacturing industries. This device is primarily used to control acceleration, deceleration, speed, and torque of an electric motor. This article will provide a clearer understanding of the application field and working principle of B7A-R6B36.

Application Field of B7A-R6B36

The B7A-R6B36 is most suitable for use in industrial applications. Examples of places it is used include material handling, metal processing, and conveyers. It is also suitable for controlling centrifuges, mixers, and pumps in the chemical, pharmaceutical, and food industries. Additionally, B7A-R6B36 can be used for the operation of synchronizing circular looms, embroiderers, and knitting machines in the textile industry.

This device is designed to provide maximum torque at low speed, as well as excellent torque characteristics in constant speed applications. It enables the user to reliably start and stop the motor, and provides the user with a smooth and accurate speed control. Because of its versatility, it can also be used to simulate a wide variety of motor load conditions.

Working Principle of B7A-R6B36

The B7A-R6B36 is a timer-type speed control that uses a thyristor as a switching element. It is a solid-state device that can be used to control both voltage and current to the motor. The working principle of the device works by varying the firing angle of the thyristor to adjust the speed of the motor.

The device includes a timer circuit, a thyristor gate pulse generator (TPG), and a protection circuit. The timer circuit is used to set the firing angle, which determines the speed of the motor. The TPG generates the thyristor gates pulses by measuring the voltage and current of the three-phase motor and creates pulses based on the set firing angle.

The device also includes an over-load protection circuit. This circuit senses the changes in the motor current and cuts off the operating voltage when the current exceeds the upper limit. This feature helps to prevent any potential damage to motor due to excessive current.

Conclusion

The B7A-R6B36 is an electric control device that is suitable for many industrial applications. It is used to control the velocity, acceleration, deceleration, and torque of an electric motor, and features a timer circuit, thyristor gate pulse generator, and over-load protection circuit. It is a reliable and efficient speed control device that can be used in many situations.
