BORRIES motor Germany BORRIES model BORRIES price

BORRIES motors are a type of electric motor powered by simultaneously connecting to 380V three-phase AC current (phase difference 120 degrees). 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, there is slip, 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. The rotor windings generate electromotive force and current due to relative motion with the magnetic field, interacting with the magnetic field to produce electromagnetic torque, achieving energy conversion.

BORRIES motor control methods

Motor vector control technology: Vector control technology emerged in the early 70 s. The vector control system for permanent magnet synchronous motors references DC motor control strategies, using coordinate transformations to decompose collected vectors such as the motor's three-phase stator currents and flux linkages into two components along the direction of the rotor flux linkage (a rotating vector). One component, aligned with the rotor flux linkage direction, is called the direct-axis excitation current; the other, orthogonal to the rotor flux linkage direction, is called the quadrature-axis torque current. By regulating the excitation current and torque current according to different control objectives, precise control over speed and torque is achieved, giving the control system good steady-state and dynamic response characteristics. Depending on the control objective, permanent magnet synchronous motor vector control algorithms can be categorized as follows: id=0 control, maximum torque per ampere control, field-weakening control, etc. These performance indicators are all achievable through independent control of the direct-axis excitation current and the quadrature-axis torque current.

BORRIES motor operating principle

When symmetrical three-phase AC current is supplied to the three-phase stator windings of a 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, inducing an electromotive force (the direction of which is determined by the right-hand rule). Because the ends of the rotor conductors are short-circuited by end rings, an induced current largely consistent in direction with the induced electromotive force is generated in the rotor conductors under the influence of the electromotive force. The current-carrying rotor conductors are subjected to electromagnetic forces within the stator magnetic field (the direction of the force is determined by the left-hand rule). These electromagnetic forces produce electromagnetic torque on the rotor shaft, driving the rotor to rotate in the direction of the rotating magnetic field. From this analysis, the operating principle of an electric motor can be summarized as follows: When three-phase symmetrical AC power is applied to the motor's three-phase stator windings (each phase shifted by 120 electrical degrees), a rotating magnetic field is produced. This rotating magnetic field cuts the rotor windings, thereby inducing current in the rotor windings (which form a closed circuit). The current-carrying rotor conductors then experience electromagnetic force under the action of the stator's rotating magnetic field, forming electromagnetic torque on the motor shaft that drives the motor to rotate, with the motor's rotation direction matching that of the rotating magnetic field.

BORRIES motor precautions

Protection of motors from oil and water. A: Servo motors can be used in locations subject to water or oil droplets, but they are not fully waterproof or oil-proof. Therefore, servo motors should not be placed or used in environments submerged in water or oil. B: If a servo motor is connected to a gearbox, an oil seal should be used when operating the servo motor to prevent oil from the gearbox from entering the servo motor. C: Do not immerse servo motor cables in oil or water. Two, Servo motor cable → Stress relief. A: Ensure that cables are not subjected to torque or vertical loads due to external bending forces or their own weight, especially at cable exits or connections. B: When the servo motor is moving, securely fix the cable (the one supplied with the motor) to a stationary part (relative to the motor), and extend it using an additional cable installed in a cable carrier to minimize bending stress. C: Keep the bend radius of the cable as large as possible. Three, Permissible shaft end load for servo motors. A: Ensure that radial and axial loads applied to the servo motor shaft during installation and operation remain within the specified values for each model. B: Exercise extreme caution when installing a rigid coupling, as excessive bending loads may cause damage or wear to the shaft end and bearings. C: It is recommended to use flexible couplings to keep radial loads below the permissible value; these are specifically designed for servo motors with high mechanical strength. D: For information on permissible shaft loads, refer to the "Permissible Shaft Load Table" (in the user manual). Four, Servo motor installation notes. A: When installing or removing coupling components on the servo motor shaft end, do not strike the shaft end directly with a hammer. (Striking the shaft end directly with a hammer can damage the encoder on the opposite end of the servo motor shaft.) B: Strive to align the shaft end optimally (misalignment may lead to vibration or bearing damage).
