Customizable low-speed self-locking Hengye motor carbon brush replaceable push rod. Low-speed self-locking DC actuator is a type of device that converts electrical energy into mechanical motion. It is designed to operate at low speeds and has a self-locking feature, meaning it can hold its position without the need for continuous power. This can be particularly useful in applications where stability or safety is a priority. Actuators are devices that produce mechanical motion in response to an electrical signal. In the case of a DC actuator, it utilizes direct current (DC) electrical power to drive its operation.
