Miniature Digital DC Servo Drive Controller for Extreme Environmental Conditions
Ultra-light and intelligent digital servo drive
Operating Modes-Current, Velocity, Position & Advance Position |
| The Bee is a highly durable series of featherweight ExtrIQ digital servo drives for DC brush and brushless motors, linear motors and voice coils.Despite weighing only .95 oz (27 g), the Bee can withstand extended environmental conditions and support up to 3.3 amps. Its high density allows the drive to deliver a peak of 400W of power and 200W of continuous power. Based on Elmo's
SimplIQ Motion Control technology, the Bee is capable of operating in position, velocity and current
modes and contains a wide range of feedback and I/O options. By using Elmo's Composer software, users can easily perform drive setup, configuration, tuning, analysis and programming. The drive operates on DC power. The Bee is a PCB mounted device which enables an efficient and cost saving implementation. |
