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.

Actuator Life- How to Estimate for Ball and Roller Screw Actuators

Estimating how long a piece of equipment will last in an application is critical information in the specification process. This step-by-step guide examines how to estimate the life of an electric actuator, utilizing ball or roller screw technology, in applications that require constant or varying (changing) loads. In addition, you will learn how to calculate life in units of time (days, years, etc.) and how to compare the expected life of two different solutions.

Live Webinar April 7 -Control Schemes for Dealing with Nonlinear Mechanics

There are many challenges when designing a motion control system. One challenge that can overwhelm many engineers is nonlinear mechanics. These mechanics can make tuning a motion control system difficult. At Galil, we pride ourselves in being able to provide intuitive solutions for these nonlinear or unorthodox mechanics. This webinar will discuss six examples of applications with nonlinear mechanics, their inherent challenges, and the tools/solutions to address these challenges.

Below are the six examples of applications with nonlinear mechanics:

  1. High-friction axis
  2. Mechanics with backlash
  3. Servo axis involving a spring
  4. Axis exposed to large and unpredictable outside forces
  5. Mechanics where inertia varies with position
  6. Hydraulic axis

Before coming to Galil, he worked at companies such as Raychem, Tyco, and EPE Industries where his technical contribution focused on mechanical design. Robin began his career at Galil assisting customers with the design of new hardware, software, and firmware for their motion control applications as well as troubleshooting existing OEM applications. In the past 16 years Robin has become the senior application engineer focusing mostly on international OEMs. Robin holds a BSME from the University of Maine at Orono.

Clutches- What you need to know


A clutch is a mechanical device that engages and disengages a power transmission, especially from a driving shaft to a driven shaft.  Clutches are used whenever the transmission of power or motion must be controlled over a time element (ie. electric screwdrivers limit how much torque is transmitted through use of a clutch).

In the simplest application, Power-on Clutches connect and disconnect two rotating shafts (drive shafts or line shafts).  In these applications, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work.  Although the typical motions involved are rotary, linear clutches are also possible.

Generating the Clutch Torque

Power-on Clutches and Brakes are designed to start and stop inertial loads when the voltage is turned on. When DC voltage is applied to the coil, the magnetic force caused by the magnetic flux pulls the armature across the air gap against the force of the zero-backlash spring attached to the armature.  The mating of the armature and rotor face produce torque.

When DC voltage is interrupted, the magnetic field collapses, and the zero-backlash spring retracts the armature from the rotor face.  Thus there is no residual torque produced.

Common Types of Clutches

Electromagnetic clutches are typically engaged by an electromagnet that is an integral part of the clutch assembly.

Magnetic particle clutches contain magnetically influenced particles in a chamber between the driving and driven members and application of direct current makes the particles clump together and adhere to the operating surfaces.  Engagement and slippage are notably smooth.

Wrap-spring clutches have a helical spring typically wound with square-cross-section wire.  The spring is fastened at one end to the driven member; its other end is unattached.  The spring fits closely around a cylindrical driving member.  If the driving member rotates in the direction that would unwind the spring, the spring expands minutely and slips although with some drag.  Because of this, spring clutches must typically be lubricated with light oil.  Rotating the driving member the opposite way makes the spring wrap itself tightly around the driving surface and the clutch locks up very quickly.

Clutches/Power-On Brake packages are used to couple two parallel or in-line shafts. The clutch armature hub can accommodate a pulley, gear, sprocket, etc., to transmit torque to the second shaft.  The brake is used to stop or hold the load.
