ATLANTA motor Germany ATLANTA model ATLANTA price

ATLANTA motors have a set of adjustable eccentric weights installed at each end of the rotor shaft, utilizing the centrifugal force generated by the high-speed rotation of the shaft and eccentric weights to obtain excitation force. Vibration motors have a wide vibration frequency range; only when the excitation power and power are properly matched can mechanical noise be reduced. Vibration motors have six classifications, such as by starting and operating mode, and by operating speed.

ATLANTA motor protection

Motor protection provides comprehensive protection for the motor, i.e., providing alarm or protection in case of overload, phase loss, locked rotor, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, stator-rotor eccentricity, axial displacement, and radial runout; the device providing protection for the electric motor is the motor protector, including thermal relays, electronic protectors, and intelligent protectors. Large and important motors generally use intelligent protection devices.

ATLANTA motor structure

Motor structures: 1, flat-type single-sided long-stator electromagnetic linear synchronous motor, where there is tangential driving force and normal attractive force 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 part of the area under each energized stator segment is covered by poles, the leakage reactance of the stator windings is large. 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 appearance similar to a rotary motor. This type of linear motor is generally of the short-primary, long-secondary type. 3, permanent magnet linear synchronous motor, which is excited by permanent magnets and combines the dual characteristics of permanent magnet motors and linear motors. Compared with linear induction motors, permanent magnet linear synchronous motors have higher mechanical performance indicators, smaller size, lighter weight, and regenerative braking function; the main disadvantages are higher cost and more complex control. 4, hybrid-excited linear synchronous motor; among linear synchronous motors, there is also an excitation system using a mix of high-performance permanent magnets and electrically excited coils, also known as controllable permanent magnet linear synchronous motors. Its main feature is that basic excitation is provided by permanent magnets, while dynamic adjustment is completed by electrical excitation, highlighting the advantage of controllability.

ATLANTA motor mechanical characteristics

Motor characteristics: With the rapid development of power electronics and new semiconductor devices, AC speed control technology has been continuously improved. Gradually perfected variable frequency drives (VFDs) are widely used in AC motors due to their good output waveform and excellent performance-to-price ratio. Large motors for rolling mills in steel plants, medium and small roller table motors, traction motors for railways and urban rail transit, elevator motors, hoisting motors for container lifting equipment, motors for water pumps and fans, compressors, household appliance motors, etc., have successively adopted AC variable frequency speed control motors, achieving good results. AC variable frequency speed control motors have significant advantages over DC speed control motors: (1) Easy speed control and energy saving. (2) AC motors have simple structure, small size, low inertia, low cost, easy maintenance, and durability. (3) Capacity can be expanded to achieve high-speed and high-voltage operation. (4) Soft start and rapid braking can be achieved. (5) Spark-free, explosion-proof, and strong environmental adaptability. In recent years, international variable frequency speed control drives have developed at an annual growth rate of 13 %～ 16%, showing a trend of gradually replacing most DC speed control drives. Since ordinary asynchronous motors working with constant frequency and constant voltage power sources have great limitations when applied to variable frequency speed control systems, specialized variable frequency AC motors designed according to usage occasions and requirements have been developed abroad. For example, there are motors for low noise and low vibration, motors with improved low-speed torque characteristics, high-speed motors, motors with tachogenerators, and vector control motors.
