Product Description:
The SC105010I3 is a brushless servo drive produced by Pacific Scientific within the SC100 Brushless Servo Controllers series. It is designed to regulate torque, velocity, and position in three-phase permanent-magnet motors used throughout industrial automation cells, material-handling axes, packaging machinery, and similar motion systems. By monitoring motor feedback and modulating its internal power stage, the controller supplies controlled current to maintain commanded motion profiles while protecting the motor and incoming power line.
The power stage operates from a nominal DC link of 320 VDC, derived from a three-phase mains input of 230 VAC that can deviate by +10% or -15% while remaining functional. Under continuous stall conditions, the amplifier delivers 40 A, supporting up to 9 kW of motor output. A shunt circuit dissipates regenerated energy, accepting 60 W continuously and up to 15 kW for 300 ms during rapid deceleration. Internal switching devices commutate at 5 kHz to minimize current ripple and acoustic noise, and overall conversion efficiency exceeds 95%, keeping heat generation low. The front end accepts supply frequencies from 47 to 63 Hz over all three phases, and full-load ratings are maintained between 0 °C and 50 °C ambient before derating is required.
During transient moves, the drive can source 60 A for five seconds, allowing motors to reach acceleration demands that peak at 17 kW. In those intervals, the IGBT bridge and bus capacitors are protected by the same shunt, and total internal losses reach only 205 W, easing cabinet cooling design. The unit can be stored at temperatures as low as -55 °C and as high as 70 °C without component damage. The three-phase input topology simplifies harmonic filtering while delivering balanced line loading to the supply.
