The motor is namely an engine. The starter rotor is driven to rotate by the energized coil in the magnetic field, and the small gear on the rotor drives the flywheel of the engine to rotate. An electric motor (Electric Motor, see Figure 1), also known as an electric motor, is an electrical device that converts electrical energy into mechanical energy and can then use mechanical energy to generate kinetic energy to drive other devices. The electric motor is mainly composed of a stator (Stator) and a rotor (Rotor). The stator is stationary in space, and the rotor can rotate around an axis and is supported by bearings. figure 1 According to the use of power can be divided into: DC Motor : Using permanent magnets or electromagnets, brushes, commutators and other components, the brushes and commutators continuously supply the externally supplied DC power to the coils of the rotor, and change the direction of the current in a timely manner , so that the rotor can continue to rotate in the same direction. AC Motor (AC Motor) : The alternating current is passed through the stator coil of the motor, and the design allows the surrounding magnetic field to push the rotor at different times and different positions to keep it running. Pulse motor : The power supply is processed by a digital IC chip and turned into a pulse current to control the motor. A stepping motor is a type of pulse motor. According to the structure is divided into : Synchronous Motor, Induction Motor, Induction Motor, Reversible Motor, Stepping Motor, Servo Motor, Linear Motor, Rotary Converter And Rotating Amplifier etc. Electric motors belong to electric motors, which meet the provisions of item 85.01 of the "Tariff Code". According to the general rules 1 and 6 of the "Tariff Code", electric motors should be classified as "electric motors" under item 85.01. The starter motor (Start The Motor, see Figure 2) refers to the motor that is installed on the engine through electric drive and is used to start the diesel and gasoline engines. It is often used for starting automobile engines, starting generators, and starting large construction machinery . The starter motor is composed of three parts: a DC motor, a transmission mechanism, and an electromagnetic switch. It converts the electric energy of the battery into mechanical energy, and drives the flywheel on the engine to rotate to start the engine. Starter motors belong to starter motors for internal combustion engines. According to the description of item 85.01 in the Notes on Tariffs: "except starter motors for internal combustion engines (item 85.11)" and the description of item 85.11: "This item includes: 6. Starter motors, which are A small electric motor, usually a DC series wound motor. A starter motor with a pinion that moves back and forth on a threaded shaft, or with some other mechanical device that temporarily couples it to the internal combustion engine to start the internal combustion engine. ", according to the general rules 1 and 6 of the "Tax Code", the starter motor should be classified under the tax code 8511.40 as "starter motor and dual-purpose starter generator". figure 2 The hydraulic motor (Hydraulic Motor, see Figure 3), also known as the oil motor, is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft, and the liquid is The medium for transmitting force and motion is mainly used in injection molding machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical, port machinery, etc. According to its structure, it can be divided into vane type, radial piston type, axial piston motor, gear motor, high-speed motor and low-speed motor. Hydraulic motors belong to hydraulic power devices, which meet the item provisions of item 84.12 of the "Tariff Code" "Other engines and power devices". Included in the tax code column 8412.2910 00. image 3 Air motor (Air Motor, see Figure 4), also known as wind motor, refers to a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy and generates rotational motion. It uses compressed air as the prime mover of the working medium, generally as Rotary power source for more complex installations or machines. According to its structure, it is divided into vane air motor, piston air motor, compact vane air motor and compact piston air motor. Pneumatic motors are pneumatic power devices, which meet the item provisions of item 84.12 of the "Tariff Code" "Other engines and power devices". No. 8412.390090. Figure 4 Minitype Vibration Motor (Minitype Vibration Motor, see Figure 5), also known as a vibration motor, is mainly used in mobile phones. It is a DC brushed motor. There is an eccentric wheel on the motor shaft. When the motor rotates, the center mass of the eccentric wheel is not in the On the center of rotation of the motor, the motor is constantly out of balance, causing vibration due to inertia. According to the description of item 85.01 in the "Tariff Notes": "This item also does not include: (2) Vibration-producing motors and electromagnetic vibrators of item 84.79", which are in line with the provisions of item 84.79 of the "Tariff Code", and refer to the classification decision D -1-0000-2005-0295 (see below), according to the general rules 1 and 6 of the "Tax Code", the micro vibration motor should be classified as "other unlisted machines and mechanical appliances (with independent functions)" in this chapter Tariff number 8479.899990.
