Description
Ultra compact Smart servo drive
Up to 50A/100V
Up to 10A/200V
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 50 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
Up to 60V
