ATR: The Fastest Direct Drive Rotary Motor by Akribis Systems

Akribis ATR Direct Drive Rotary Motor

Akribis ATR Direct Drive Rotary Motor

The ATR is another revolutionary direct drive motor from Akribis Systems.  The patent-pending design provides the motor with super high torque and low rotor inertia at the same time.

In our ATR design, we replaced the conventional rotor back iron with another set of coils.  The removal of the back iron significantly reduced the rotor inertia.  And the additional inner coils result in much higher torque output.  These combined features give ATR unparalleled dynamic performance.

Features include:

  • Super high torque and low rotor inertia
  • Excellent dynamic performance
  • Fastest direct drive rotary motor
  • Various sizes with air/water cooling options
  • Ideal for indexing applications

Applimotion UTS Slotless Direct Drive Motor

For the ultimate in smooth operation when scanning or positioning, the UTS Series Slotless motors offer zero cogging and sinusoidal torque angle curves.  Considered one of the best motor constructions for many years, Applimotion has leveraged already proven motor technology as the basis for this new family of direct drive motors.  Once you have taken advantage of a slotless direct drive motor you won’t go back to traditional motors.  Features include:

  • Wide Range of Diameters – from 29 mm to 240 mm.
  • Medium motor constant – Low phase resistance and inductance for the motor size optimizes operation with low voltage power supplies and provides the high output with minimum voltage drop.
  • Optional Windings – Select your voltage, speed and current, Applimotion will create a special winding to optimize torque or efficiency.
  • Sinusoidal Torque Curves – motor designs for optimum performance with sinusoidal current control. Less than 1% higher harmonic content for minimum torque ripple on sinusoidal drives
  • Zero Cogging Torque – provides ultra-smooth consistent motion.
  • Optional Back Iron Rings – A standard set of iron rings are offered for each motor.
  • Optional Hall Device Feedback – internally mounted PCA doesn’t add to motor height offered on some motors, others require externally mounted hall device board.

Do you know the difference between these 10 types of servomotors?

Servomotors are generally used as a high performance alternative to the stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps. This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. This lack of feedback though limits their performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors. The encoder and controller of a servomotor are an additional cost, but they optimize the performance of the overall system (for all of speed, power and accuracy) relative to the capacity of the basic motor. With larger systems, where a powerful motor represents an increasing proportion of the system cost, servomotors have the advantage….

Theory, Application & Operation of Frameless Motor Technology. Live Webinar.

February 23, 2016  11:00 AM ET

Register to watch the webinar on or after February 23.

For many years there seems to have been an engineering mystique surrounding the integration of frameless motor part sets into high performance machine design. This has kept many machine design engineers from jumping in to embed these power and torque dense motor types into their applications.

This webinar will focus on the integration of frameless motors into practical machine design challenges. We will touch on the background and use of embedded motor components, typical application overview, performance improvement expectations, typical design and installation best practices, drive amplifier and feedback considerations, and machine system thermal concerns.

We will also review some basic tools available to help design engineers optimize frameless motor performance in customer machine applications.

Meet the Speaker:

New Torque Motor Family from Tecnotion

Tecnotion adds QTR Frameless Torque Motors to its direct drive product offering.  With low axial height and high torque density, the QTR bridges the size-performance gap.

Direct Drive Motors, also know as Torque Motors, are permanent-magnet direct drive motors that rotate along an axis.  They can be used wherever a rotary movement is required and offer numerous advantages over conventional servo drives.

Torque Motors from Tecnotion are extremely compact, provide an extremely stiff drive train, eliminate the need for time-consuming mounting procedures, are virtually maintenance free and can be integrated directly into the machine structure, while the spacious open inner diameter enables wire and cable feedthrough.  To top things off the entire series comes with completely sealed stators and integrated temperature protection and measurement sensors.

Tecnotion QTR

The direct drive technology of brushless torque motors is an ideal way to enhance productivity, accuracy, and dynamic performance of applications.  This technology lowers costs, shrinks space requirements, and reduces wear and tear.  Torque motors eliminate the need for mechanical transmission components such as gearboxes, belts and speed reducers.  This reduces transmission losses and eliminates the cost and maintenance required for additional components.  And because there is no contact between rotor and stator, there is no mechanical wear, meaning less maintenance and longer life.

Tecnotion QTR Product Overview

Tecnotion QTR Product Overview

At first glance the QTR series stands out because of its cast design, which differentiates it from other torque motors by providing a low thermal resistance and very high torque density, as seen in the QTR’s very flat design, large inner diameter and low stator and rotor mass.  All motors come equipped with integrated temperature sensors and high voltage insulation.  Rather than flying leads, the QTR series is provided with braided power and sensor cables with strain relief integrated in the stator housing, reducing the rate of wear and potential failure.

The QTR motor series offers a very flat design for lower axial height and high torque density.  Features such as a large inner diameter, strain-relieved cable exit, integrated temperature sensors, low thermal resistance, and low stator and rotor mass differentiate the QTR products from other torque motors currently available.

With three outer diameters – 105, 133, and 160 mm – and five build heights, ranging from 17 mm to 92 mm, the QTR series suits applications in markets such as Semiconductor, Medical, Machine Tool, Printing, Rotary tables, Factory Automation, and Robotics. Continuous torque ranges from 1.4 to 63.5 Nm, and speed ranges from 190 rpm to 6918 rpm.

Applimotion’s LARC Motors for Large Diameter Direct Drive projects

Applimotion routinely scales its LARC motors (Linear Arc) for large diameter applications greater than 1 meter diameter. The modular nature of these motors allows them to integrate with large assemblies for scanning, imaging, and metrology applications where size requirements take priority over high torque requirements.

Applimotion LARC Motor

Applimotion LARC Motor

LARC motors come in modular pieces and will bolt into any large diameter servo motor application. The motors operate from standard brushless motor amplifiers from 24 to 300 volts. They work nicely with encoders, resolvers, or the recently introduce magnetic encoders for direct drive applications.

The LARC motors also offer very low profile design to fit into tight spaces where traditional motors have limitations. Applimotion also offers hermetically sealed magnet tracks and coil assemblies for vacuum or special environments.
