Hornet

Highly Compact and Intelligent Digital Servo Drive

Ideal for DC brush and DC brushless motors for sinusoidal commutation

The Hornet is a highly durable series of miniature ExtrIQ digital servo drives for DC brush and brushless motors, linear motors and voice coils.

The matchbox-sized servo drives weighs only 1.8 oz (50 g) but can withstand extended environmental conditions and support up to 20 amps continuous current. Its high density allows the drive to deliver a peak of 3.2 kW of power and 1.6 kW of continuous power.

Based on Elmo's SimplIQ technology, the Hornet 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 Hornet is a PCB mounted device that enables efficient, and cost saving implementation.

Mating Power Supply ELP-30.
