12V PWM DC Motor Speed Controller Switch 20A Current

This part consists of a ring gear and a matching gear or rotor. The ring gear and the casing are fixedly connected together, and the entering from the port pushes the rotor to revolve around a central point. This slow-rotating rotor drives the output through a splined shaft to become a cycloid hydraulic motor. After the advent of this cycloid motor, after decades of evolution, another concept of motor also began to form. This motor has rollers installed in the built-in ring gear. Motors with rollers provide high starting and running torque. The rollers reduce friction and thus improve efficiency. Even at very low speeds, the output shaft is Can produce stable output. By changing the direction of input and output flow, the motor is quickly reversed and an equivalent torque is generated in both directions. Each series of motors has various displacement options to meet the requirements of various speeds and torques. The working principle of the starter The control device of the car starter includes the electromagnetic switch, the starter relay and the ignition starter switch light components, among which the electromagnetic The switch is made together with the starter. 1. Electromagnetic switch 1. Structural characteristics of electromagnetic switch The electromagnetic switch is mainly composed of two parts: the electromagnet mechanism and the motor switch. The electromagnet mechanism consists of a fixed iron core, a movable iron core, an attracting coil and a holding coil. The fixed iron core is fixed, and the movable iron core can move axially in the copper sleeve. A push rod is fixed at the front end of the movable iron core, a switch contact plate is installed at the front end of the push rod, and the rear section of the movable iron core is connected with the fork by adjusting screws and connecting pins. A reset spring is installed on the outside of the copper sleeve, and the function is to reset the movable parts such as the movable iron core.
