Motor


A motor is an electromagnetic device that converts electrical energy into mechanical energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter "M" (the old standard uses "D"). Its main function is to generate a driving torque, serving as the power source for electrical appliances or various mechanical devices.


  • Classification:

    • According to the type of working power supply, it can be divided into direct - current (DC) motors and alternating - current (AC) motors. DC motors can be further divided into brushless DC motors and brushed DC motors according to their structure and working principle. AC motors can be divided into single - phase motors and three - phase motors.

    • According to the structure and working principle, it can be divided into DC motors, asynchronous motors, and synchronous motors.

    • According to the starting and operating mode, it can be divided into capacitor - start single - phase asynchronous motors, capacitor - run single - phase asynchronous motors, capacitor - start - and - run single - phase asynchronous motors, and split - phase single - phase asynchronous motors.

    • According to the purpose, it can be divided into driving motors and control motors.

    • According to the rotor structure, it can be divided into cage - type induction motors and wound - rotor induction motors.

    • According to the operating speed, it can be divided into high - speed motors, low - speed motors, constant - speed motors, and speed - regulating motors.



  • Working Principle: The direction of the force on the conductor is determined by the left - hand rule. This pair of electromagnetic forces forms a torque on the armature, which is called the electromagnetic torque in a rotating motor. If this electromagnetic torque can overcome the resistance torque on the armature, the armature can rotate.


Starter


A starter, also known as a starter motor, is a device used to rotate an internal combustion engine to initiate its operation under its own power5.


  • Function Principle5: Internal combustion engines are feedback systems that rely on the inertia of each cycle to initiate the next cycle after starting. To start the first cycle, the first two strokes need to be powered by an external force, and this is the role of the starter. Once the engine starts running and the feedback loop becomes self - sustaining, the starter is no longer needed.

  • Development History5: Before the appearance of the starter motor, engines were started by various methods, such as winding springs and human - powered crank handles. The first electric starter was installed on an Arnold in 1896. In 1911, Charles F. Kettering and Henry M. Leland of the Dayton Engineering Laboratories Company (Delco) invented the first electric starter in America and obtained a U.S. patent. In 1912, Cadillac first installed starters on production models, and then this system was widely adopted.


Starters can be electric, pneumatic, or hydraulic5. The electric starter motor is the most common type, which is usually a DC motor with a pinion gear on its shaft6. It converts the electrical energy of the battery into mechanical energy to turn the engine6.
