Reliance Electric BLJM-020/5RM2200 Servo Motor, 200W TESTED

The BLJM-020/5RM2200 is a BLJM series brushless AC servo motor manufactured by Reliance Electric (also branded under Baldor and later part of Rockwell Automation / ABB systems). These motors are typically used in high-performance industrial automation systems, CNC machinery, and motion control applications. This model features: High torque density in a compact frame Rugged construction for industrial environments Designed to operate with compatible Reliance Electric servo drives (e.g., Automax / SP series drives) Parameter Specification Motor Series BLJM (Brushless AC Servo Motor) Model Number BLJM-020/5RM2200 Frame Size 020 (approx. NEMA 23 equivalent) Voltage 220V AC (nominal, 3-phase) Rated Speed ~3000 RPM (typical for BLJM motors) Peak Speed Up to 6000 RPM (depending on load/drive) Rated Torque ~0.6 – 1.0 Nm (estimated for BLJM-020 series) Peak Torque ~2.5x rated torque (typical for this series) Feedback Device Resolver (common in 5RM series) Insulation Class Class F Mounting Type Flange mount Shaft Type Smooth shaft with keyway (varies) Cooling Method Natural convection (TENV enclosure) Enclosure Totally Enclosed, Non-Ventilated (TENV) Weight Approx. 3–5 kg (depending on configuration) Encoder/Feedback Feedback Type: Resolver (5RM = Resolver, Multiturn capable) This motor requires a compatible drive that can interface with resolver signals (e.g., Reliance SP or Automax drives).
