SHA-CG Hollow Shaft Actuators from Harmonic Drive LLC

Harmonic Drive LLC, a leader in high precision motion control introduces new actuators with surface run-out less than 10 microns. The SHA-CG  models are the newest offerings in the company’s Rotary Acutator product category.

Harmonic SHA-CG Actuator

Harmonic SHA-CG Actuator

The SHA-CG actuators feature a compact, hollow shaft configuration for design versatility in demanding applications. Ideal for machine tool applications, the SHA Series of brushless actuators provide high torque for fast acceleration and positioning. SHA-CG actuators are composed of a Harmonic Drive® CSG zero-backlash gear combined with a brushless servomotor with an encoder resolution at the output up to 20,971,520 pulse/rev.

The actuators are also available with an optional brake. Positional accuracy better than 1 arc-min and repeatability better than ±5 arc-sec is achieved while delivering up to 3,400 N m of torque. A robust cross-roller bearing allows mounting of large loads directly to the actuator without the need for additional support.

The SHA-CG has a Torque to Weight ratio as much as 8 times greater than comparable housed direct drive motors, and a Torque to Volume ratio as much as 6 times greater. This allows for a more compact and light-weight machine design.

Known for its expert engineering and manufacturing, Harmonic Drive LLC products are relied upon every day for precision motion control.

SHA-CG Specifications:

  • High Accuracy:  Zero-backlash Harmonic Drive® gear reducer
  • Hollow Shaft diameter:   17-45mm
  • Available in 4 sizes, 20, 25, 32, 40
  • Maximum speed up to 120 rpm
  • Design: Compact, flat, hollow shaft

Slotless Zero Cogging Motor Kits from AppliMotion feature ultra smooth operation

Applimotion’s UTS Series Slotless Direct Drive Frameless Motors are permanent magnet 3phase ring type, low profile, direct drive motors with large through hole available in 29-240mm diameters.

Applimotion UTS Slotless Direct Drive Motor

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.

Positioning Stages for Vacuum Applications

Lintech custom vacuum stageLintech provides many different sized positioning tables, each available with lots of standard options.  One option which is not described much in any Lintech literature is that most of the screw driven tables offered can be supplied, in a customized variation, to meet some pretty significant vacuum environments.  Lintech has made many positioning tables for vacuum applications.  All of the standard components not already able to withstand vacuum environments can be substituted for the appropriate stainless product.

Lintech builds vacuum capable tables utilizing modified standard models or with complete custom designs.  As usual, the customer just needs to supply the application requirements and then Lintech try to use a “standard” table if suitable; otherwise a custom will be offered.

Should you be in need of a linear motion table capable of some type of vacuum environment, please contact Electromate for a Lintech solution.

Introducing Galil’s New H-Bot Firmware

There are many applications that require movement in planar space, or movement along two perpendicular axes. This two dimensional system can be fitted with additional motors to increase the number of degrees of freedom. These types of applications can range from specimen positioning for a microscope and 3D printers to product packaging and material application.

The most common way that planar motion is achieved is using a machine based on the XY stage or gantry system. This type of system can have many drawbacks which will be outlined later in this article. An alternative to these types of machines is the H-Bot which has many advantages when compared to XY stages or gantries.

This article will discuss the advantages and disadvantages of using an H-Bot for systems that use planar movement as well as Galil’s H-Bot firmware solution for the DMC-40×0.

Introducing µZ Plug-In Servo Drives from Advanced Motion Controls

µZ’s are the smallest off-the-shelf servo drives from ADVANCED Motion Controls. Pronounced ‘Micro-Z’ these plug-in drives are designed for embedded applications in a wide range of industries including: Robotics, Lab Automation, Homeland Security/Military, Electric Mobility, Medical and Packaging.

µZ servo drives are designed to drive brushless and brushed DC motors at a high switching frequency.  To increase system reliability and to reduce cabling costs, the drives are designed for direct integration into your PCB.  Weighing in at less than 9 grams, µZ Drives output 10A peak and 5A continuous and operate with a bus voltage range of 10-36VDC.

Designed without the need for a heatsink, the µZ’s are true featherweights with a high power to weight ratio.  The µZ’s are fully protected against over-voltage, under-voltage, over-current, over-heating, and short-circuits. Depending on the model, the drives interface with digital controllers that have analog ±10V or PWM/Direction commands. These servo drives require only a single unregulated isolated DC power supply, and are fully RoHS (Reduction of Hazardous Substances) compliant.

Datasheets and Support:

AZB10A4 for ±10V Command Signals, Current Mode

AZBH10A4 for ±10V Command Signals, Hall Velocity Mode

AZBD10A4 for ±10V Command Signals, Duty Cycle Mode

AZBDC10A4 for PWM/Direction Command Signals

Stand-alone (drives with built-in interface)

AZB10A4IC for ±10V Command Signals, Current Mode

AZBDC10A4IC for PWM/Direction Command Signals

Features:

  • Designed for direct board-to-board integration.
  • No heatsink and no need for additional heatsinking results in the smallest installed volume
  • Feather weight, less than 9 grams
  • Dimensions (mm) 38.1 x 38.1 x 7.34 for current mode models, 43.2 x 38.1 x 9.4 for velocity / duty cycle models
  • Dimensions (in) 1.50 x 1.50 x 0.29 for current mode models, 1.70 x 1.50 x 0.37 for velocity / duty cycle models
  • Large operational temperature range, 0-85°C
  • Compatible with low inductance motors
  • Smallest form factor of any off-the-shelf servo drive from ADVANCED Motion Controls
