Energy-saving conveniently controlled motor control circuit

Abstract

The invention discloses an energy-saving conveniently controlled motor control circuit. The circuit comprises triodes from the first triode to the fourth triode, a first diode, a second diode, a light emitting diode, a first transformer, a second transformer, a triple switch, a button switch, resistors from the first resistor to the seventh resistor, relays from the first relay to the fourth relay, capacitors from the first capacitor to the fourth capacitor, a first rectifier, a second rectifier and a bulb. According to the energy-saving conveniently controlled motor control circuit, the multiple relays are employed for mutual cooperation and control and are applied to control circuit of a rotation mechanical driving motor. The energy-saving conveniently controlled motor control circuit has the advantages of simple circuit structure, low cost, more convenient and safer control of the driving motor, and better energy conservation, thereby having popularization and application values.

Description

technical field [0001] The invention relates to a motor control device, in particular to a motor control circuit with convenient control and energy saving. Background technique [0002] Electric motors are a type of rotating machinery. Rotating machinery refers to machinery that mainly relies on rotating actions to complete specific functions. Typical rotating machinery includes steam turbines, gas turbines, centrifugal and axial compressors, fans, pumps, water turbines, generators and aviation Engines, etc., are widely used in electric power, petrochemical, metallurgy, aerospace and other sectors. The main vibration faults of rotating machinery include unbalance, misalignment, friction and looseness, etc. Large rotating machinery is generally equipped with vibration monitoring protection and fault diagnosis system, while the existing technology is used to control the motor by the control circuit of the driving motor of rotating machinery Not safe enough, not energy-efficie...
