Miniature Military Analog Servo Amplifier for Extreme Environmental Conditions
Current mode servo amplifier for sinusoidal commutation of brushless motor
Advanced Unipolar PWM Switching method
The Raven is a series of miniature ExtrIQ current mode servo amplifiers for brushless motors. Although highly compact, the Raven can withstand extended environmental conditions and support up to 15 amps. This high power density servo amplifier
can deliver up to 2400W of peak power or 4800W of continuous power in a miniature package. The servo amplifier offers
significant operating features including excellent output linearity and zero dead band performance. The Raven is a PCB mounted device which enables efficient and cost saving implementation. |
