Scope of application

Products in this series offer several advantages, including distinct gear positions, reliable performance, a compact structure, an aesthetically pleasing appearance, a small size, easy installation, and convenient maintenance.

The operating mechanism is equipped with an automatic reset mechanism and a zero – position self – locking mechanism. Additionally, potentiometers or encoders can be added. Through the associated electronic control system, functions such as starting, speed regulation, braking, reversing, and other special operations of the motor can be achieved.
