introduction：What is a three-phase asynchronous motor： Three-phase induction motor（Triple-phase asynchronous motor）It is a kind of induction motor，Its by simultaneous access380VThree-phase alternating current（Phase difference120The degree of）A type of electric motor supplied with electricity，Because the rotor and stator of the three-phase asynchronous motor rotate the magnetic field in the same direction、Different speed into rotation，There is a slip，So its called three-phase asynchronous motor。The speed of the rotor of the three-phase asynchronous motor is lower than that of the rotating magnetic field，Due to the relative motion between the rotor winding and the magnetic field, electromotive force and current are generated，And interact with the magnetic field to produce electromagnetic torque，Realize energy conversion。 Compared with single-phase asynchronous motor，The operation performance of three-phase asynchronous motor is good，And can save a variety of materials。According to the rotor structure，Three-phase as

introduction：Rotary cylinder Rotary cylinder—That is, the inlet and exhaust pipe and the air guide head are fixed, and the cylinder body can be rotated relative to each other and act on a cylinder on a machine tool fixture and a wire crimper，It is a cylindrical metal part that guides the piston to move in a straight line。Rotary cylinder mainly by the air head、Cylinder block、Piston and piston rod composition。When the rotary cylinder is working，External forces drive the cylinder、Cylinder head and air deflector turn，The piston and piston rod can only be used for reciprocating linear motion，And the external nozzle of the air guide head，immobile。

introduction：Motor startersort： one、WGQSeries cage motor solid soft starter two、WYQSeries liquid resistance starter three、WLQSeries high pressure cage motor starter Motor starter definition： Motor starter，Is used to assist motor starting equipment，Make the motor start smoothly，The impact on the power grid is small，It can also realize the soft stop of the motor、immobilize、Overload and phase loss protection。Motor starter is mainly used in large motor and asynchronous motor。The distance between the plates makes the liquid resistance value always meet the requirements of the mechanical characteristics of the motor for the series resistance value during the starting process，Thus, the motor obtains large starting torque and small starting current，Further smooth start。The specific working process is：When the main motor starts，The moving plate moves slowly under the drive of a small power transmission mechanism system，Change the distance between the two plates，The change of the resistance value of the liquid resistance in th

introduction：The so-called permanent magnet stepper motor，Its actually calledPMStepper electricity。The rotor adopts permanent magnet steel。The stator of the stepper motor is machined into claw tooth pole by stamping，The rotor adopts radial multi-pole magnetizing permanent magnet steel。This kind of motor is cheap。 principle：The magnetic field generated by the coil current direction repels the rotor magnetic field，Thus, the motor is turned forward/reversal。 Permanent magnet stepper motor is divided into2phase，4phase，Smaller torque and volume，There are the following types of stepping angles：5.625°/7.5°/11.25°/15°，A motor has two parts: a rotor and a stator：Generally, the stator is a coil，The rotor is a permanent magnet；Or the stator can be a permanent magnet，Rotor is coil。
