Dragonfly Servo Amplifier from Elmo Motion ControlDragonfly Servo Amplifier from Elmo Motion Control

Ultralight Current Mode Servo Amplifier

Ideal for trapezoidal commutation.

The Dragonfly is a series of ultralight ExtrIQ current mode servo amplifiers for DC brush and brushless motors.

Weighing only 0.76 oz (21.5 g), the Dragonfly can withstand extended environmental conditions and can support up to 3.3 amps continuous current. This high power density servo amplifier can deliver up to 480 W of peak power or 240 W of continuous power.

The servo amplifier offers significant operating features, including excellent output linearity and zero dead band performance. The Dragonfly is a PCB mounted device that enables efficient, cost saving implementation.
