Servo Solutions for Mobile Automation Challenges. On-Demand Webinar

YouTube Video-  57minutes

With automation expanding out of the factory, machine builders are faced with a varying set of new challenges. Mobile platforms, such as unmanned systems, are expected to operate in extreme environments and carry their own power source; all while being light weight and compact.

To meet the current and future needs of the market, enabling technologies need to be applied and discovered. At the forefront of the enabling technologies are servo drive controllers.

Servo controllers not only make a robot or mobile platform move, they can also be solutions to the other design requirements. A servo is an integral component to any mobile solution and can help with power efficiency, communication, agility and dexterity. This webinar will touch on the challenges presented to robot designers and how servo drives can make them successful.

About the webinar

What’s behind every great robot? A great motor or even multiple motors, for starters. It also involves the bearings, cables, drives, and controllers, and in some cases, linear actuators. Whether your robot is being deployed on a factory floor, in an operating room, or in one of the now-famous drones, it’s these technologies that serve as the differentiators. In fact, robotics can be in applications that range from the very coarse to the very fine. For that reason, the types of motors and other components must also vary widely.

Attend this webinar and learn about:

  • The different components that are available, specifically for robotics applications
  • How the components differ
  • How you can choose the most appropriate parts for your robotic application
  • The efficiencies that can be gained by making the right choice

High Efficiency Motors

Reprint of maxon motor USA October 14, 2014 white paper

To understand the concept of high efficiency motors, you must first know how to calculate efficiency and the losses associated with the motor components themselves.

The final measured efficiency of a motor is calculated based only on the elements of the particular application they’re used in.  For the motors themselves, without a load, manufacturers provide ratings based on standard formulas.  To understand high efficiency motors you only need to know what makes them different.

But first, let’s look at the basic concept used for explaining motor efficiency, which says that efficiency is the ratio between the shaft output power and the electrical input power.  Shaft output can be measured in horsepower or watts. We’ll use watts for the purposes of this article.  The formula most often used is the simple one mentioned above:

ηm = Pout / Pin

where

ηm = motor efficiency
Pout = shaft power out (Watts)
Pin = electric power to the motor (Watts)

Once you’ve used this formula and found your efficiency – and it’s not 100 percent – it’s time to consider the losses that occurred inside the motor.  Motor efficiency drops based on a number of known factors where power is lost as current through the motor is met with a variety of resistances.  These losses can include the wiring and its resistance, iron losses due to magnetic events, and thermal losses.

The electrical power that is lost in the primary rotor and in the secondary stator windings are called resistance losses (or copper losses, because they are based on the characteristics of the wire used including its diameter and length).  Both primary and secondary resistance losses vary with the load in proportion to the current squared. For example:

Pcl = R I2

where

Pcl = stator winding, copper loss (W)
R = resistance (Ω)
I = current (Amp)

Other losses include, iron losses, as mentioned above.  These losses are the result of the amount of magnetic energy dissipated when the motor’s magnetic field is applied to the stator core.  Other factors involved include mechanical losses, which involve the friction in the motor bearings and stray losses, which are basically any remaining losses that are left after the resistance, iron, and mechanical losses are calculated.

The largest culprit for stray losses are the result of harmonic energies that are generated when the motor operates under load.  The load affects the shaft power output, which is why it’s impossible to discuss in a general article such as this.  But basically, these losses are dissipated as currents in the windings, harmonic flux components in the iron parts, and leakage in the laminate core.

High Efficiency Motors

The maxon high efficiency motors get their name because they provide efficiencies in the 90 percentiles as opposed to the 50 to 60 percent range for most motors in their class.

The key to high-efficiency for maxon lies in the fact that they have no iron losses. maxon manufactures ironless core or coreless motors designed to the needs of their customers.  This means that the losses associated with the iron components have been eliminated.  By designing coreless and ironless core motors, maxon also eliminated the largest concentration of stray losses associated with motors, which are losses associated with leakage in the laminate core.

maxon incorporates the use of permanent magnets in their motors.  The ironless core brush motors have a permanent magnet, then a rotating winding, and then the housing, which closes the magnetic path.  With this configuration, there is no electricity going through the core of the motor (through the iron parts) to create a magnetic resonance.

The benefits of the ironless winding provides very specific advantages, which include: there is no magnetic detent and there are minimal electromagnetic interferences.  Part of the efficiency, though, is dictated by the type of magnet used in the design.  For example, the stronger magnets, such as NdFe will offer higher efficiencies.  Add to this, the fact that maxon includes graphite brushes and ball bearings in their brushed motors, customers gain long service life as well as high efficiency.

Brushless servo motors – more control for valves with linear actuators

Reprint of blog posted by Ryan Klemetson of Tolomatic on Tue, Mar 24, 2015 @ 08:03 AM

Many process industry control engineers are looking to more sophisticated motion control solutions for valve automation. That’s because there’s an ever-growing need to improve productivity, increase efficiency and minimize downtime. It’s essential that engineers be able to control the valves that regulate the flow of materials throughout a facility.

There are three basic types of step motors: variable reluctance, permanent magnet and hybrid.  A hybrid step motor is a simple low cost means of providing good motion performance.  Step motors are electromechanical devices that work by dividing shaft rotation into discrete distances called steps. Basically, they are brushless motors which include permanent magnet variable reluctance and hybrid types.  Most step motors are hybrids and feature 200 steps per revolution (1.8 degrees). The magnetic structure of the motor is designed to be incremental in nature i.e one pulse to the motor causes the armature to move one complete step.  At power up, a hybrid step motor could rotate up to ±3.6 degrees in either direction due to the rotor having 200 natural detent positions….

Pre-recorded Webinar. EtherCAT as a Master Machine Control Tool

YouTube 50minute Video by Galil Motion Control

Topics include an overview of the communication scheme, physical layout and applications where EtherCAT is the right solution.

There is an increasing demand in the automation and motion control industries for a localized motion control solution that can coordinate motion between multiple remote components. Previously, field bus protocols such as Modbus or Ethernet/IP have been implemented to address remote I/O connectivity. Although successful in moving data across automation networks, these protocols lacked the real time performance necessary for a distributed motion control system.

The EtherCAT communication protocol provides a high speed, low overhead communication scheme that allows efficient, deterministic communication between motion controller and remote components. Based on CANOpen and streamlined specifically for point to point transmission of real time data, the EtherCAT standard is quickly becoming the preferred choice for centralized control of tightly coupled motion between remote components. This presentation is aimed at designers of automation and motion control systems with a basic understanding of Ethernet/IP and EtherCAT communications. Topics will include an overview of the communication scheme, physical layout and applications where EtherCAT is the right solution.
