Description

Elmo’s Servo Motors

Elmo’s Servo Motors for applications in a broad range of standard and specialized projects are very versatile thanks to its various feedback types:

  • STD (default): Single turn 20 bits Absolute Encoder
  • Option: Multi-turn, 20 bits single turn + 16 bits multi-turn, including battery
  • Option: Quadrature 2500 ppr+ commutation signals (Hall signals)

There are other options that are available upon specific request.

types of servo motor

As safety becomes a main aspect of technology, Elmo Servo Motors are evolving by directly integrating many safety solutions.

They are designed to meet most machines safety directives and standards. The motors are STO (Safety Torque Off) certified (IEC 61800-5-2:2007 SIL, EN ISO 13849-1:2008 Cat 3, PLe) and have a Brake Option which allows for “internal” brake control and powering.

Our servo motors are extremely rugged, compact and are equipped for tough environmental conditions, allowing high performance for operation directly from the mains.

Regarding Elmo servo drives, peak output operation is twice the rated continuous current for a full three seconds in certain drives.

This has been a clear advantage for Elmo for some time since many manufacturers can only rate peak operation at one second or less. This allows for a wide variety of applications, for use of Servo motors with expanded dynamic performance.

Since connectivity is a key aspect in compatibility, our servo motor offers a variation of application support for the most popular Ethernet fieldbuses including EtherCAT and CANopen.

These capabilities make networking highly efficient and highly compatible for the use of most machines.

Servo Motors Highlights:

Elmo’s superior motion control drives enable achieving the highest results from the Servo Motor in the most demanding machines and challenging applications (AC servo motor, torque servo motor, etc.).

  • Compact design
  • Low cogging rotation
  • High operating efficiency
  • Wide power range: standard 50W to 1000W (up to 5kw are available upon request)

The motors are durable, extremely versatile and used in a wide range of applications and industries.

Perfectly Integrated Combined Servo Drives and Motors

In addition to the high standards of Elmo servo drives and servo motors, Elmo provides the perfected harmony between servo drive and motor, with the integrated servo motor and drive – The Gold Duet .

These range of models offer a variety of:

  • Servo motor flange sizes between 40 to 110 mm
  • Perfectly tuned
  • Integrated
  • Balanced with the appropriate servo drive to optimize the servo motor characteristics
  • Saves space and cabling in complex applications

The Gold Duet are a series of integrated digital servo drives and motors which are highly resilient and designed to deliver maximum power density and intelligence.

The Gold Duet delivers up to 1500W of continuous power and 4500W peak power in a compact high quality package.

The digital servo drives integrated in the Gold Duet are designed for use with any type of sinusoidal and trapezoidal commutation, with vector control. The Gold Duet can operate as a stand-alone device or as part of a multi-axis system in a distributed configuration on a real-time network. In a real-time network, the Gold Duet displays its real benefits, as configuring the network is practically as simple as plug and play with some fine-tuning required to adapt the network specifically to the requirements of the customer application.

Power to the drives is provided by an isolated Mains DC power source. The Gold Duet can operate with single power or dual power supplies.
