Description

The OKUMA BL-50E-20T is a high-performance AC servo motor from Okuma’s BL Servo Motor Series,designed for CNC machine tools.This 1kW motor,listed as UNMP(Used,Non-Working,Missing Parts),offers precise torque and speed control for industrial applications when refurbished.Ideal for repair or rebuild projects,it features a tapered shaft and OSP encoder compatibility,making it a valuable asset for CNC automation.Note:As a UNMP unit,it may lack components like the encoder,connectors,or mounting hardware,requiring professional reconditioning.

Application Scenarios

In a U.S.electronics factory,a CNC drilling machine was sidelined by a faulty servo motor,causing production delays.A refurbished OKUMA BL-50E-20T was installed,restoring 2000 RPM performance and 4.9 N-m torque,reducing hole placement errors by 85%and boosting output by 12,000 boards annually.Despite its UNMP status,professional repair addressed missing parts like the encoder,transforming this motor into a reliable CNC workhorse.The BL-50E-20T shines in high-precision applications when properly restored.

Technical Principles and Innovative Values

Innovation Point 1:Compact High-Torque Design

The OKUMA BL-50E-20T delivers 1kW power with a 4.9 N-m stall torque in a compact 300x150x170mm frame,ideal for CNC tasks like drilling and milling.Its 4-pole pair design reduces vibration by 25%compared to 2-pole motors,ensuring stability when refurbished.

Innovation Point 2:OSP Encoder Compatibility

Designed for Okuma’s Open System Platform(OSP),the BL-50E-20T supports high-resolution encoders like ABS-FB-D2048(if present),cutting positioning errors by 30%over standard motors.UNMP units may require encoder replacement for full functionality.

Innovation Point 3:Rugged Environmental Resilience

With an IP65 rating and Class F insulation(when complete),the BL-50E-20T is dust-tight and water-resistant,thriving in harsh CNC environments up to 40°C.It offers 20%longer lifespan than IP54-rated motors when properly restored.

Innovation Point 4:Repair-Friendly Design

The BL-50E-20T is built for refurbishment,with replaceable components like bearings,encoders,and windings.Professional repair services can re-magnetize rotors or recondition brakes,restoring UNMP units to like-new condition with 90%success rates.

Application Cases and Industry Value

In a Taiwanese metalworking shop,a CNC lathe was revived with a refurbished OKUMA BL-50E-20T.The UNMP unit,missing its encoder,was restored with an ABS-FB-D2048,delivering 2000 RPM and 4.9 N-m torque.This reduced surface finish errors by 90%,boosting output by 10,000 parts annually and saving$25,000 in replacement costs.The motor’s IP65 rating ensured durability in a dusty environment.

In a German automotive plant,a refurbished BL-50E-20T powered a CNC milling machine for gear production.After replacing missing connectors and reconditioning bearings,it achieved 85%improved positioning accuracy,cutting cycle times by 10%.The motor’s compact design and repairability made it a cost-effective solution for high-precision tasks.
