Reliance Electric 3RA2003 Brushless AC Servo
 |
The Reliance Electric 3RA2003 is a 3‑HP brushless AC servo controller from the HR2000 series, rated for 230 V/180 V AC three‑phase input with a stall torque of 54 lb‑in and a maximum speed of 3000 rpm. Common failure points in this class include overheating due to inadequate ventilation (thermal resistance 0.57 °C/W), phase loss or overcurrent on the motor windings, and degradation of the internal power MOSFETs or IGBT modules. Initial checks should verify that the supply voltage is within spec and stable, inspect the controller’s cooling fan and heat sink for dust buildup, and review any fault codes displayed on the panel or communicated via the drive’s diagnostic interface.[oss-gpt-20b] |
