Motors, solenoids, and driver boards/modules are electromechanical components that convert electrical energy into mechanical motion or force. Motors generate rotational movement, solenoids produce linear motion, and driver boards/modules control the operation of these devices. These components are critical in automation, robotics, industrial machinery, and consumer electronics, enabling precise control of mechanical systems.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| DC Motors | Continuous rotation, speed controlled by voltage | Robotics, electric vehicles |
| Stepper Motors | High precision position control | 3D printers, CNC machines |
| Servo Motors | Feedback-controlled angular position | Industrial automation, drones |
| Linear Solenoids | Direct linear force output | Valve actuators, door locks |
| Rotary Solenoids | Convert linear motion to rotational | Automotive starters, industrial machinery |
| H-Bridge Drivers | Bi-directional motor control | DC motor direction control |
| PWM Driver Modules | Speed control via pulse-width modulation | Fan speed controllers, robotics |
Electric Motors: Consist of stator (stationary magnetic field), rotor (rotating component), bearings, and housing. Brushed types use commutators, while brushless variants employ electronic commutation.
Solenoids: Composed of coil windings, plunger (movable iron core), spring return mechanism, and protective enclosure. Electromagnetic field generated by coil current moves the plunger.
Driver Boards: Include power transistors (MOSFET/IGBT), microcontroller interfaces, current sensing circuits, and thermal protection components. Modular types integrate these elements in compact PCB assemblies.
