Whistle

Highly compact and intelligent digital servo drive
(Up to 20 A/100 V and up to 10 A/200 V)

The Whistle is a series of intelligent miniature digital servo drives for DC brush and brushless motors, linear motors and voice coils. The matchbox-sized servo drive weighs only 1.8 oz (50 g) and supports up to 20 amps continuous current. Its high density allows the drive to deliver a peak of 3200 W of power and 1600 W of continuous power. Based on Elmo's SimplIQ Motion Control technology, the Whistle is capable of operating in position, velocity and current modes and contains a wide range of feedback and I/O options. With Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power. The Whistle is a PCB mounted device that enables efficient and cost saving implementation.

Elmo also offers a range of Whistle-based products including:

  • The DUO and TRIO - integrated Whistle solutions that provide the power of two and three Whistle servo drives, respectively, in a single board
  • the Whistle Evaluation Board
