2.2Product Description
The Raven is a series of miniature ExtrIQ current mode servo amplifiers for brushless motors with sinusoidal commutation. Although highly compact, the Raven can withstand extended environmental conditions and support up to 35 Amps. This high power density servo amplifier can deliver up to 4800 W of peak power or 2400 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 Raven incorporates custom mixed analog/digital ICs and a hybrid power stage. The basic configuration is a current mode amplifier targeting the OEM market. As such, no trimmers are used in the basic version. In addition to its compliance with relevant MIL standards, the Raven amplifier also meets UL508c and the relevant CE regulations.
The Raven power stage is implemented on a single ceramic substrate. This design enables very high thermal conductivity, high current carrying capacity, improved EMC and good mechanical strength. The control section is implemented by dedicated custom ICs that contribute to enhanced performance.
