DK-621-0940-4S, which is a kind of general industrial electric actuators, can have a wide range of application and diversified working principles. It can be mainly applied to regulating valve, textile machinery, air conditioning and some other industries.

It is mainly composed of motor, gearbox and mechanical components. Adopting a brushless DC motor, the motor shell is made of high-strength aluminum alloy, which increases the rigidity and has good heat dissipation. The brushless DC motor can be coupled with a helical gear reducer, that can be both sustain high-speed operation and large transmission ratio. The outer casing is made of aluminum alloy and advanced engineering plastic, which are components that can help increase the stability of the actuator.

The most common working principle of DK-621-0940-4S is that the motor will receive the signal to rotate the armature at the specified speed, the rotational motion will be translated to the output shaft through the gear reducer, the output shaft will drive the required mechanical component. For example, a valve stem connected to the output shaft can be opened and closed by the linear motion of the spindle.

After the motor power on, the given command current will be inputted into the brushless DC motor through a specially designed controller, the motor will run in a certain direction and speed, the gearbox will output the specific torque. The output shaft of the gearbox is connected with the mechanical components then works with the help of the momentum. If the components experience a heavy load, the motor current will increase, this increase will feedback to the controller, the controller will then reduce the output current and adjust the speed.

Moreover, DK-621-0940-4S also integrated with precise displacement control technology which makes it have a higher precision in the positioning, starting and stopping and make sure the operation will go smoothly. In addition, its waterproof design and common connectivity make it applicable for low temperature or special environment.

DK-621-0940-4S can be widely applied to valve switch and adjustable speed drive for textile extracting, printing, dyeing, air conditioning and other industrial process, as well as some other machines. With its high torque, high power, high external torque, good acceleration, better heat dissipation, speedy response, precise position control, waterproof and weatherproof design, this DK-621-0940-4S has proven to be a preferable choice for many people who are using some machines that are required to operate with precision or in harsh environment.
