UTS Slotless Frameless Motors have low magnetic core losses

Applimotion’s new UTS Series direct drive slotless motors now cover 29-240 mm diameters with thin radial length, prefect for direct drive positioning or high speed spindle applications.  Driven by customer demand and new applications in gimbal and imaging systems, Applimotion has expanded the range of their slotless motor line up.

Aces at scanning or precision positioning, slotless motors are hand down provide the smoothest motion available.  True sinusoidal torque curves seamlessly integrate with sinusoidal motor controller electronics to create fully controllable smoothly rotating torque vector.

These motors remain true to their ULT ultra-thin origins with very low profile construction.  They operate from industry standard brushless DC or brushless AC drivers from 12-300 volts and can be wound for low speed or high speed applications.

Another feature of these motors is low magnetic core losses.  Slotless motors in general are optimum for high speed operation, above 10krpm.  The frameless nature of these motors also allows them to easily be integrated into high speed spindles where they can operate with very low heating.

Features include:

  • Wide Range of Diameters – from 29 mm to 240 mm. Special sizes can also be created with short lead time.
  • 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 – cogging torque has plagued many applications, motor suppliers continue to fight the manufacturability battle to reduce cogging and keep motors consistent.
  • Optional Back Iron Rings – A standard set of iron rings are offered for each motor. Optional rings are available allowing more options for higher integration.
  • Optional Hall Device Feedback – internally mounted PCA doesn’t add to motor height offered on some motors, others require externally mounted hall device board.

High performance servo motor in a small package

maxon sets new standards in micro drives

maxon’s smallest DC brushless motor is only four millimeters in diameter and comes in two different lengths. Certified in accordance with ISO 13485, the new brushless micro drive is ideal for medical applications.

Maxon EC4 Brushless Gearmotor

Maxon EC4 Brushless Gearmotor

The EC 4 brushless DC motor is maxon motor’s ultra-compact solution to the market’s needs. As the smallest micromotor to come from the Swiss manufacturer, the EC 4 is only four millimeters in diameter. It is available in two lengths, with power ratings of 0.5 and 1 W. Equipped with an ironless maxon winding, the EC 4 stands out for its robust design, high power density, and energy efficiency.

maxon has the matching gearhead

Combined with the GP 4 planetary gearhead, the EC 4 becomes a compact drive for use in micropumps, analytic and diagnostic devices, and laboratory robots. Precise and reliable, it can adjust lenses, dispense fluids, or position sensing devices. All units meet the ISO 13485 medical standard, which makes this maxon micro drive the perfect choice for applications in medical technology.

Closed-Loop Stepper Motor Performance Gains

A New White Paper from Galil Motion Control

Galil White Paper PicModern motion controllers can include the ability to run stepper motors with encoder feedback, resulting in true closed-loop motion control. This mode of motor control is very similar to standard three-phase brushless servo motor control, where the three phases are offset 120 electrical degrees. With steppers, the motor has two phases offset by 90 electrical degrees. The benefits of closed-loop control with stepper motors include greatly improved velocity smoothness and reduced power consumption compared to open-loop steppers and much higher torque at low velocity compared with traditional three-phase brushless servo motors…
