Autz + Herrmann motor, German Autz + Herrmann model, Autz + Herrmann price

Autz + Herrmann motors are devices that convert electrical energy into mechanical energy. They utilize energized coils (i.e., stator windings) to generate a rotating magnetic field that acts on the rotor (such as a squirrel-cage closed aluminum frame) to form electromagnetic rotational torque. Motors are classified into DC motors and AC motors based on the power supply used. Most motors in power systems are AC motors, which can be synchronous or asynchronous (the stator magnetic field speed and rotor rotation speed do not remain synchronized). The motor mainly consists of a stator and a rotor. The direction of force-induced motion of current-carrying conductors in a magnetic field depends on the current direction and the direction of magnetic flux lines (magnetic field direction). The working principle of the motor is the force exerted by the magnetic field on the current, causing the motor to rotate.

Autz + Herrmann motor classification

Motors fall into two categories: reluctance type and Sawyer type. The Sawyer linear stepper motor consists of a stationary part (called the reaction plate) and a moving part (called the mover). The reaction plate is made of soft magnetic material with uniformly distributed teeth and slots. The motor's mover consists of permanent magnets and two coil-equipped magnetic poles A and B. The mover is supported by an air cushion to eliminate mechanical friction during movement, ensuring smooth operation and improved positioning accuracy. The maximum travel speed of this motor can reach 1.5 m/s, acceleration can reach 2g, and positioning accuracy can exceed 20 micrometers. Two Sawyer linear stepper motors assembled perpendicular to each other form a planar motor. By applying different combinations of control currents to the motors in the x direction and y direction (Figure 3), the motor can perform arbitrary geometric trajectory movements within the plane. Large automatic plotters are new devices combining computers and planar motors. Planar motors can also be used in laser cutting systems, with control precision and resolution reaching tens of micrometers.

Autz + Herrmann motor classification

The motor swaps the stator and rotor of a conventional DC motor. Its rotor uses permanent magnets to generate air gap flux; the stator serves as the armature, composed of multi-phase windings. Structurally, it resembles a permanent magnet synchronous motor. The stator structure of a brushless DC motor is identical to that of conventional synchronous or induction motors. Multi-phase windings (three-phase, four-phase, five-phase, etc.) are embedded in the iron core. Windings can be connected in star or delta configurations and linked to the inverter's power transistors for proper commutation. Rotors often use rare-earth materials such as samarium-cobalt or neodymium-iron-boron, which have high coercivity and high remanence. Due to different placements of magnetic materials in the poles, they can be classified as surface-mounted, embedded, or ring-shaped poles. Since the motor body is a permanent magnet motor, brushless DC motors are commonly referred to as permanent magnet brushless DC motors. Brushed DC motors: The 2 brushes (copper or carbon) of a brushed motor are fixed to the motor's rear cover via an insulating seat, directly introducing the positive and negative power supply terminals to the rotor's commutator. The commutator connects the coils on the rotor, and the continuous alternating polarity of the 3 coils interacts with the 2 fixed magnets on the housing to generate rotational force. Since the commutator is fixed to the rotor and the brushes are fixed to the housing (stator), friction between the brushes and commutator during rotation generates significant resistance and heat. Consequently, brushed motors suffer from low efficiency and high losses. However, they offer advantages such as simple manufacturing and low cost.

Autz + Herrmann 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, slip exists, hence the name three-phase asynchronous motor. The rotor speed of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. Relative motion between the rotor windings and the magnetic field induces electromotive force and current, which interact with the magnetic field to produce electromagnetic torque, achieving energy conversion. Compared to single-phase asynchronous motors, three-phase asynchronous motors offer better operating performance and save various materials. Based on rotor structure, three-phase asynchronous motors are divided into squirrel-cage and wound-rotor types. Squirrel-cage asynchronous motors feature simple structure, reliable operation, light weight, and low cost, leading to widespread application; their main disadvantage is difficult speed regulation. Wound-rotor three-phase asynchronous motors have three-phase windings on both the rotor and stator, connected to external rheostats via slip rings and brushes. Adjusting the rheostat resistance can improve starting performance and regulate motor speed.
