Rexroth 144-201-000-222 Servo Power Drive Board

Product Description

Bosch Rexroth (Indramat) 144-201-000-222 is a servo power stage board for legacy Indramat digital servo drives. It is the main power conversion unit. It converts DC bus voltage into PWM three-phase output to drive permanent magnet synchronous servo motors. It integrates IGBT power module, current sampling, gate drive circuit and hardware overcurrent protection. PCB with conformal coating. It samples phase current in real time and cooperates with the control board to realize torque / speed / position closed-loop control. Widely used in legacy CNC machines, multi-axis printing presses and special automation lines. It is rare MRO spare part for Indramat systems.
