Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an energy-saving automatic control motor. Background Technology

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol M) and generators (symbol G).

[0003] 1) DC motors can be classified into brushless DC motors and brushed DC motors according to their structure and working principle.

[0004] Brushed DC motors can be classified into two types: permanent magnet DC motors and electromagnetic DC motors.

[0005] Electromagnetic DC motors can be classified into: series-wound DC motors, shunt-wound DC motors, separately excited DC motors, and compound-wound DC motors.

[0006] Permanent magnet DC motors can be classified into three types: rare earth permanent magnet DC motors, ferrite permanent magnet DC motors, and AlNiCo permanent magnet DC motors.

[0007] 2) AC motors can be further divided into single-phase motors and three-phase motors.

[0008] 2. According to structure and working principle, motors can be divided into DC motors, asynchronous motors, and synchronous motors.

[0009] 1) Synchronous motors can be classified as: permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors.

[0010] 2) Asynchronous motors can be divided into: induction motors and AC commutator motors.

[0011] Induction motors can be classified as: three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors, etc.

[0012] AC commutator motors can be classified as: single-phase series motors, AC / DC universal motors, and repulsion motors.

[0013] 3. According to the starting and running methods, single-phase asynchronous motors can be divided into: capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors.

[0014] 4. According to their purpose, electric motors can be divided into drive motors and control motors.

[0015] 1) Electric motors for driving can be divided into: electric motors for power tools (including tools for drilling, polishing, grinding, grooving, cutting, and reaming), electric motors for household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.), and electric motors for other general-purpose small mechanical equipment (including various small machine tools, small machinery, medical devices, electronic instruments, etc.).

[0016] 2) Control motors are further divided into stepper motors and servo motors, etc.

[0017] 5. According to the rotor structure, induction motors can be divided into: squirrel-cage induction motors (formerly known as squirrel-cage asynchronous motors) and wound-rotor induction motors (formerly known as wound-rotor asynchronous motors).

[0018] 6. According to operating speed, motors can be classified as: high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors. Low-speed motors are further divided into geared motors, electromagnetic geared motors, torque motors, and claw-pole synchronous motors, etc.

[0019] In addition to being classified into stepped constant speed motors, stepless constant speed motors, stepped variable speed motors, and stepless variable speed motors, speed-regulating motors can also be classified into electromagnetic speed-regulating motors, DC speed-regulating motors, PWM frequency conversion speed-regulating motors, and switched reluctance speed-regulating motors.

[0020] The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.

[0021] The rotor speed of a synchronous motor remains constant regardless of the load.

[0022] However, the power of current motors is rated and set before leaving the factory. Therefore, such motors can only operate within the rated voltage range and cannot adjust the power to drive the motor according to actual needs. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content
