PARVALUX motor Germany PARVALUX model PARVALUX price

PARVALUX motors are a new generation of gear reduction motors, featuring compact size, low noise, maintenance-free operation, and an attractive appearance. The speed ranges from 0.83r/min to 300r/min. This series of low-speed motors is a new high-tech product that integrates electromagnetic drive and reduction mechanisms within the motor housing. The low speed and high torque directly meet customer requirements without the need for additional reduction devices. The motor uses Class B and Class F insulation, with protection ratings of IP44 and IP55, and voltages of 220V and 380V.

PARVALUX motor structure

Motor structures: 1, flat-type single-sided long-stator electromagnetic linear synchronous motor, where tangential driving force and normal attractive force exist between the mover and stator of the flat-type single-sided long-stator linear synchronous motor. Motor excitation can be changed by adjusting the current magnitude in the mover pole windings. During operation, the long-stator windings are switched on in segments; since only a portion under each energized stator segment is covered with poles, the leakage reactance of the stator windings is relatively high. Part of the supply voltage is used to overcome the leakage reactance voltage drop. 2, cylindrical linear synchronous motor, which is a cylindrical linear motor with an external shape similar to that of a rotary electric machine. This type of linear motor generally adopts a short-primary, long-secondary configuration. 3, permanent magnet linear synchronous motor, which uses permanent magnets for excitation and combines the characteristics of both permanent magnet motors and linear motors. Compared with linear induction motors, permanent magnet linear synchronous motors offer higher mechanical performance indices, smaller size, and lighter weight, and feature regenerative braking capability; their main disadvantages are higher cost and more complex control. 4, hybrid-excited linear synchronous motor, in which some linear synchronous motors adopt an excitation system combining high-performance permanent magnets with electrically excited coils, also known as controllable permanent magnet linear synchronous motors. Its main characteristic is that the basic excitation is provided by permanent magnets, while dynamic adjustment is achieved through electrical excitation, highlighting the advantage of controllability.

PARVALUX motor working principle

When symmetrical three-phase AC current is supplied to the three-phase stator windings in the motor, a rotating magnetic field is generated that rotates clockwise in the space between the stator and the inner circle of the rotor at synchronous speed n1. Since the rotating magnetic field rotates at n1 speed and the rotor conductors are initially stationary, the rotor conductors cut the stator's rotating magnetic field, generating an induced electromotive force (the direction of the induced electromotive force is determined by the right-hand rule). Since the two ends of the rotor conductors are short-circuited by end rings, an induced current basically consistent in direction with the induced electromotive force is generated in the rotor conductors under the action of the induced electromotive force. The current-carrying conductors of the rotor are subjected to electromagnetic force in the stator magnetic field (the direction of the force is determined by the left-hand rule). The electromagnetic force produces electromagnetic torque on the rotor shaft, driving the rotor to rotate in the direction of the rotating magnetic field. From the above analysis, the working principle of the motor can be summarized as follows: When three-phase symmetrical AC current is supplied to the three-phase stator windings of the motor (with a phase difference of 120 electrical degrees), a rotating magnetic field is generated. This rotating magnetic field cuts the rotor windings, thereby generating induced current in the rotor windings (the rotor windings form a closed circuit). The current-carrying rotor conductors generate electromagnetic force under the action of the stator's rotating magnetic field, thereby forming electromagnetic torque on the motor shaft, driving the motor to rotate, with the motor rotation direction being the same as the rotating magnetic field direction.

PARVALUX motor mechanical characteristics

Because the rotor of a three-phase asynchronous motor rotates in the same direction but at a different speed than the stator's rotating magnetic field, resulting in slip, it is called a three-phase asynchronous motor. The rotor speed of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor windings generate electromotive force and current due to relative motion with the magnetic field, and interact with the magnetic field to produce electromagnetic torque, achieving energy conversion. Compared with single-phase asynchronous motors, three-phase asynchronous motors have better operating performance and save various materials. Depending on the rotor structure, three-phase asynchronous motors can be divided into squirrel-cage and wound-rotor types. Squirrel-cage asynchronous motors have simple structure, reliable operation, light weight, and low price, leading to widespread application; their main disadvantage is difficult speed regulation. Wound-rotor three-phase asynchronous motors have three-phase windings on the rotor similar to the stator, connected to external rheostats via slip rings and brushes. Adjusting the rheostat resistance can improve the motor's starting performance and regulate the motor speed.
