LAT Antriebstechnik motor Germany LAT Antriebstechnik model LAT Antriebstechnik price

LAT Antriebstechnik motors are permanent magnet motors commutated or controlled by current via electronic circuits. Permanent magnet brushless motors come in two types: sine wave drive and square wave drive. Those with rectangular wave drive current are commonly referred to as permanent magnet brushless DC motors, while those with sine wave drive current are commonly referred to as permanent magnet AC servo motors. Based on sensor type, they can be classified into sensor-equipped motors and sensorless motors.

LAT Antriebstechnik motor applications

Motor variable frequency speed control has become the mainstream speed regulation solution and can be widely applied to stepless speed transmission in various industries. Particularly with the increasingly widespread use of variable frequency drives (VFDs) in industrial control, the use of variable frequency motors has also grown. It can be said that due to the superiority of variable frequency motors over standard motors in variable frequency control, wherever VFDs are used, variable frequency motors are commonly seen. The social benefits of domestically produced high-voltage variable frequency devices are significant, mainly including energy saving, thereby conserving resources and reducing environmental pollution. They eliminate starting shocks to motors and impacts on the power grid, reduce failure rates of motors and equipment, and improve control precision and automation levels. The economic benefits of variable frequency speed control are also very significant. For pumps and fans, fluid flow is proportional to the first power of speed, torque is proportional to the square of speed, and power is proportional to the cube of speed. As speed decreases, motor power consumption drops by the cube, making the energy-saving effect of variable frequency speed control very significant. If flow is reduced, speed drops, head drops, and motor power consumption drops, theoretically saving energy. If dampers or valves were originally used for regulation, flow decreases while head increases, and motor power decreases; thus, variable frequency speed control saves more energy than damper or valve regulation. In addition to energy efficiency, there are indirect economic benefits for different loads, mainly including improved power factor, soft start implementation, reduced electrical and mechanical damage to motors from starting torque, and smooth, stable, high-precision control.

LAT Antriebstechnik motor classification

Motors are classified into three-phase and single-phase types based on the number of phases. For the same volume, the output of a three-phase reluctance synchronous motor is 1/3 to 2/3 higher than that of a single-phase reluctance synchronous motor. Single-phase reluctance synchronous motors can be further divided into capacitor-start, capacitor-run, and capacitor-start-and-run types based on the starting method. Capacitor-start motors have high starting torque. Capacitor-run motors offer good running performance, high efficiency, high power factor, and low noise, but have lower starting torque. Capacitor-start-and-run motors combine the advantages of both, offering relatively high starting torque and good running performance. A reluctance synchronous motor is a type of micro synchronous motor. Its rotor structure is salient-pole, appearing as a cylinder or disc. The entire rotor is assembled from magnetic and non-magnetic materials. The magnetic reluctance in the direct axis is lower than in the quadrature axis, creating a salient-pole magnetic effect. When the stator winding is energized, a rotating magnetic field is generated in the air gap. Under the influence of this rotating magnetic field, magnetic pull is produced, dragging the rotor to rotate synchronously. A reluctance synchronous motor is a synchronous motor with an unexcited rotor featuring several regularly shaped protrusions, equipped with or without a squirrel-cage winding for starting. It is also known as a switched reluctance motor. A reluctance motor is equivalent to a salient-pole synchronous motor without excitation windings, generating electromagnetic torque by utilizing differences in magnetic reluctance in the rotor magnetic circuit.

LAT Antriebstechnik motor working principle

The working principle of the motor is based on the DC series-wound motor. The principle is shown in Figure 1. The field winding and armature winding are connected in series to a DC power supply. Based on the direction of the main magnetic flux Φ and the armature current Ia, the direction of rotor rotation can be determined using the left-hand rule; in a, it rotates counterclockwise. If the polarity of the power supply is reversed, as shown in Figure 1b, since it is a series-wound motor, both the main magnetic flux Φ and the armature current Ia change direction simultaneously. According to the left-hand rule, the rotor direction remains unchanged, still rotating counterclockwise. Therefore, when a single-phase AC voltage is applied to a series-wound motor, as shown in Figure 1c, although the power supply polarity changes periodically, the rotor maintains a constant direction of rotation. Thus, series-wound motors can be used with both AC and DC power sources. Single-phase series-wound motors belong to single-phase AC asynchronous motors and are dual-use for AC and DC, so they are also called AC/DC universal series-wound motors. Due to their high speed, compact size, high starting torque, and adjustable speed, they can be used on both DC and single-phase AC power sources, leading to widespread application in power tools. The motor mainly consists of three parts: stator, rotor, and bracket. The stator consists of a salient-pole iron core and field windings. The rotor consists of a non-salient-pole iron core, armature windings, commutator, and shaft. The field winding and armature winding form a series circuit through brushes and the commutator.
