Anaheim motor Germany Anaheim model Anaheim price

Anaheim motors are electromagnetic devices that convert or transmit electrical energy in accordance with the law of electromagnetic induction. The term broadly refers to all machines capable of converting mechanical energy into electrical energy, or electrical energy into mechanical energy. The motor housing has an ingress protection rating of IP44, and the cooling method is IC0141 totally enclosed fan-cooled (TEFC). Ambient air temperature varies with the seasons but does not exceed 15℃ to 40℃. Altitude does not exceed 1000m. Rated frequency, rated voltage, insulation class, and duty cycle are specified on the nameplate. When the supply voltage varies within ±0.05 of the rated value (with frequency at the rated value), the motor's output power remains at the rated value.

Anaheim motor classification

Broad classification of motors: Motor types are highly diverse. AC motors can be categorized as low-speed or high-speed. Low-speed variants are referred to as low-speed motors or AC low-speed motors; high-speed variants are called high-speed motors, high-speed electric motors, or AC high-speed motors. High-speed motors are also known as motorized spindles or high-speed motorized spindles. The motorized spindle is a recent technology in the CNC machine tool sector that integrates the machine spindle and spindle motor into a single unit. Together with linear motor technology and high-speed tooling technology, it is ushering high-speed machining into a new era. A motorized spindle is an assembly comprising the spindle itself and its accessories: the motorized spindle, high-frequency inverter, oil-mist lubricator, cooling unit, built-in encoder, and tool-changing mechanism. Motorized spindles typically use hybrid ceramic bearings, which are wear-resistant and heat-resistant, offering several times the service life of traditional bearings. Electromagnetic suspension bearings or hydrostatic bearings are sometimes used; since the inner and outer rings do not contact each other, theoretical service life is infinite. The motorized spindle is the product of integrating an electric motor with the spindle; the motor rotor serves as the rotating part of the spindle. Theoretically, a motorized spindle can be regarded as a high-speed electric motor. The key technology is dynamic balancing at high speeds. Lubrication for motorized spindles generally uses timed, metered oil-air lubrication. Grease lubrication is also possible, but requires a reduction in speed. 'Timed' means injecting oil at fixed time intervals. 'Metered' means precisely controlling the volume of lubricating oil per injection using a device called a metering valve. Oil-air lubrication refers to lubricating oil being blown into the ceramic bearing by compressed air. Oil volume control is critical: too little fails to provide adequate lubrication; too much causes heating due to oil resistance during high-speed bearing rotation. Cooling unit: To dissipate heat from the high-speed motorized spindle as quickly as possible, the outer wall of the spindle is typically circulated with a coolant. The cooling unit maintains the coolant temperature. To enable automatic tool changing and rigid tapping, the motorized spindle incorporates a pulse encoder for accurate phase angle control and synchronization with feed motion. For application in machining centers, the motorized spindle is equipped with an automatic tool-changing mechanism, including disc springs and a tool-pulling hydraulic cylinder, among others. The widely known BT and ISO tooling systems have been proven unsuitable for high-speed machining. In such cases, high-speed tooling systems such as HSK and SKI have emerged. To achieve rotational speeds of tens of thousands or even over one hundred thousand RPM for the motorized spindle, a high-frequency inverter must drive the built-in high-speed motor. The inverter's output frequency must reach hundreds or thousands of Hertz.

Anaheim motor principle

When a symmetrical voltage is applied to the motor stator windings, a rotating air-gap magnetic field is generated. The rotor winding conductors cut this magnetic field, inducing an electromotive force (EMF). Since the rotor windings are short-circuited, a rotor current is produced. The interaction between the rotor current and the air-gap magnetic field generates electromagnetic torque, thereby driving the rotor to rotate. The motor speed is always lower than the synchronous speed of the magnetic field, because only then can the rotor conductors induce EMF, thereby generating rotor current and electromagnetic torque. Therefore, this motor is called an asynchronous motor, also known as an induction motor. The motor speed (rotor speed) is less than the speed of the rotating magnetic field, hence the term asynchronous motor. It is essentially the same as an induction motor. s = (ns-n) / n, where s is the slip ratio, ns is the magnetic field speed, and n is the rotor speed. There are many types of asynchronous motors, including explosion-proof three-phase asynchronous motors, ys series three-phase asynchronous motors, y, y2 series three-phase asynchronous motors, and YVP series variable-frequency speed-control motors.

Anaheim motor advantages

The motor consists of the motor body and the driver, representing a typical mechatronic product. The motor stator windings are mostly configured in a three-phase symmetrical star connection, very similar to three-phase asynchronous motors. Permanent magnets, already magnetized, are attached to the motor rotor. To detect the polarity of the motor rotor, position sensors are installed inside the motor. The driver comprises power electronic devices and integrated circuits. Its functions include: receiving start, stop, and brake signals from the motor to control starting, stopping, and braking; receiving signals from position sensors and forward/reverse commands to control the switching of power transistors in the inverter bridge, thereby generating continuous torque; receiving speed commands and speed feedback signals to control and adjust rotational speed; and providing protection and display functions.
