Piccolo

Miniature PWM Analog DC Servo Amplifier

Ideal for DC brushless motors with trapezoidal commutation

The Piccolo is a series of miniature current mode servo amplifiers for DC brushless motors with trapezoidal commutation. Although highly compact, the Piccolo can support up to 25 amps continuous current. This high power density servo amplifier can deliver up to 5800W of peak power or 2900 W of continuous power in a miniature package.

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