ANIMATICS motor Germany ANIMATICS model ANIMATICS price

ANIMATICS motors consist of the motor body and the driver, representing a typical mechatronic product. Brushless motors refer to motors without brushes and commutators (or slip rings), also known as commutator-less motors. As early as the nineteenth century, when motors were first invented, the practical motors produced were of the brushless type, namely AC squirrel-cage asynchronous motors, which were widely used. However, asynchronous motors have many insurmountable defects, resulting in slow development of motor technology. In the mid-twentieth century, transistors were invented, leading to the emergence of DC brushless motors that use transistor commutation circuits to replace brushes and commutators. This new type of brushless motor is called an electronically commutated DC motor, which overcomes the defects of the first generation of brushless motors.

ANIMATICS motor applications

Motors are primarily used in digital control systems, offering high precision and reliable operation. When position detection and speed feedback are employed, closed-loop control can also be achieved. Stepper motors have been widely applied in digital control systems, such as in digital-to-analog conversion devices, CNC machine tools, computer peripheral equipment, automatic recorders, and clocks. They are also used in industrial automation production lines and printing equipment. A stepper motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the motor's speed and stopping position depend solely on the frequency and number of pulse signals, unaffected by load variations. That is, each pulse signal applied to the motor causes it to rotate by one step angle. The existence of this linear relationship, combined with the fact that stepper motors exhibit only periodic errors without cumulative error, makes using stepper motors for speed and position control very straightforward. Although stepper motors are widely used, they cannot be operated under conventional conditions like ordinary DC or AC motors. They require a control system composed of dual-ring pulse signals and power drive circuits to function. Therefore, effectively utilizing stepper motors is not easy, as it involves extensive professional knowledge in mechanics, motors, electronics, and computing. Nowadays, while there are indeed many manufacturers producing stepper motors, very few have specialized technical personnel capable of independent development and research. Most manufacturers have only ten to twenty employees and lack even the most basic equipment, operating merely at a stage of blind imitation. This causes considerable trouble for users in product selection and usage. In view of the above situation, we have decided to take the widely used variable-reluctance stepper motor as an example to describe its basic working principle, hoping to assist a broad range of users in product selection, usage, and overall equipment improvement.

ANIMATICS motor applications

Motors have broad application prospects in the following aspects: (1) High-speed motors are used in various occasions such as centrifugal compressors in air conditioners or refrigerators. With the development of science and technology, special requirements are increasing, and their applications will become more widespread. (2) With the development of hybrid electric vehicles in the automotive industry, small-sized, lightweight high-speed generators will receive significant attention and have good application prospects in hybrid electric vehicles, aviation, ships, and other fields. (3) Gas turbine-driven high-speed generators are compact and highly maneuverable. They can be used as backup power for important facilities, or as independent power sources or small power stations to compensate for the shortcomings of centralized power supply, having important practical value. Since the centrifugal force on the rotor of a high-speed motor is proportional to the square of the linear velocity, high-speed motors require high mechanical strength. Additionally, due to the high frequency and high iron losses in high-speed motors, the magnetic flux density in the iron core should be appropriately reduced during design, and low-loss iron core materials should be used. Bearing research is also closely related to high-speed motors, because ordinary bearings struggle to withstand long-term operation in high-speed systems; thus, bearings with new materials and structures must be used. High-speed motors can have various structural forms, such as induction motors, permanent magnet motors, and reluctance motors. The centrifugal force is very large when the motor rotates at high speed. When the linear velocity reaches 200m/s or above, conventional laminated rotors cannot withstand the centrifugal force generated by high-speed rotation, requiring special high-strength laminated or solid rotors. In the nearly hundred-year history of rotor dynamics development, many calculation methods have emerged. Modern calculation methods can mainly be divided into two categories: the transfer matrix method and the finite element method. The finite element method offers concise and standardized expressions of motion equations and has many advantages in solving rotor dynamics problems or complex mechanical systems composed of rotors and surrounding structures. The finite element method involves massive discretization of complex rotor systems, and its calculation results are more accurate than those of the transfer matrix method; however, it requires long computation times and occupies large memory. The development of modern computer technology has provided good hardware support for the finite element method.

ANIMATICS 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 reactive synchronous motor is 1/3 to 2/3 higher than that of a single-phase reactive synchronous motor. Single-phase reactive 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 the above two types, featuring relatively high starting torque and better running performance. A reactive synchronous motor is a type of micro synchronous motor. Its rotor structure is salient-pole; externally, it appears as a cylinder or disc. The entire rotor is assembled from magnetic and non-magnetic materials. The reluctance in the direct axis direction is less than that in the quadrature axis direction, creating a salient-pole magnetic effect. When the stator winding is energized, a rotating magnetic field is generated in the air gap. Under the action of this rotating magnetic field, magnetic pull is produced, dragging the rotor to rotate synchronously. A reactive synchronous motor is a synchronous motor whose rotor has no excitation but has several regularly shaped protruding parts, equipped with a cage winding for starting or without one. It is also known as a reluctance motor. A reluctance motor is equivalent to a salient-pole synchronous motor without excitation windings, generating electromagnetic torque by utilizing the difference in magnetic reluctance in the rotor magnetic circuit.
