Infranor Mavilor BLS-073 Brushless Servo Motor – High Torque Density, IP65 Rated, In Stock!

Description

Product Introduction

The Infranor Mavilor BLS-073 is a high-performance brushless servo motor engineered for dynamic, high-precision motion control applications across industrial automation. As part of the BLS (BrushLess Servo) series from Infranor’s legacy Mavilor brand—renowned for robust electromechanical design—the Infranor Mavilor BLS-073 combines compact dimensions with exceptional torque density, low rotor inertia, and smooth operation across its entire speed range. Its frame-integrated 24-bit absolute encoder eliminates the need for battery-backed memory or homing routines at startup, making it ideal for applications requiring immediate position awareness.

Designed for seamless integration into both new and retrofit systems, the Infranor Mavilor BLS-073 operates efficiently on 400 VDC bus architectures commonly found in modern servo drives from Delta, Bosch Rexroth, and even legacy Indramat systems with proper parameter tuning. The motor’s natural convection cooling and IP65-rated housing allow reliable deployment in harsh environments—such as food packaging lines, textile machinery, or printing presses—where exposure to dust, moisture, or cleaning agents would compromise lesser motors. With minimal cogging torque and high-resolution feedback, the Infranor Mavilor BLS-073 delivers the responsiveness and repeatability demanded by today’s high-speed automation tasks.

Core Advantages and Technical Highlights

Exceptional dynamic response: The Infranor Mavilor BLS-073 features an optimized electromagnetic design with low electrical time constant and minimal rotor inertia, enabling rapid acceleration and deceleration without overshoot. This makes it especially effective in indexing tables, pick-and-place robots, and flying shear applications where cycle time directly impacts throughput.

Integrated high-resolution absolute feedback: Unlike incremental encoders that require homing after power loss, the Infranor Mavilor BLS-073 includes a factory-calibrated 24-bit absolute encoder (typically EnDat 2.2 or BiSS-C interface), providing true single-turn position data instantly at power-up. This reduces machine startup time, enhances safety in coordinated axes, and supports advanced drive features like electronic gearing and cam profiling without external sensors.

Robust mechanical construction: Housed in a stiff, cast aluminum body with precision-ground flange (IEC standard), the Infranor Mavilor BLS-073 resists vibration and thermal deformation during continuous operation. The IP65 rating ensures protection against dust ingress and low-pressure water jets—critical in washdown environments like bottling or meat processing. Shaft sealing and double-shielded bearings further extend service life under heavy radial/axial loads.

Broad drive compatibility: Although originally designed for Infranor’s Xcelerator drives, the Infranor Mavilor BLS-073 has proven interoperability with third-party amplifiers due to its standardized winding characteristics and feedback protocols. Engineers have successfully commissioned it with Delta A2-M series, Bosch Rexroth IndraDrive Cs, and even Kollmorgen AKD drives—provided motor parameters (Ke, R, L, inertia) are accurately entered.

Maintenance-free and quiet operation: With no brushes to wear out and a fanless design, the Infranor Mavilor BLS-073 operates silently and requires no routine maintenance beyond periodic bearing inspection (recommended every 20,000 hours). Its sinusoidal back-EMF waveform ensures smooth torque delivery, reducing mechanical stress on couplings and gearboxes—extending the entire motion system’s lifespan.

Typical Application Scenarios

In flexible packaging machines, the Infranor Mavilor BLS-073 drives film unwind/rewind spindles and transverse sealers where precise tension control and rapid speed changes are essential to prevent web breaks or misprints. Its absolute encoder allows instant synchronization after emergency stops—minimizing material waste. Similarly, in digital textile printers, the Infranor Mavilor BLS-073 powers the print carriage axis, delivering consistent velocity at high resolution to avoid banding or color misregistration, while its IP65 rating withstands ink mist and cleaning solvents.

In automated assembly cells, the Infranor Mavilor BLS-073 is frequently used in SCARA robot joints or linear gantry axes requiring sub-micron repeatability and fast settling times. Because it retains absolute position through power cycles, it eliminates the need for limit switches or vision-based homing—streamlining cell restart after maintenance. For legacy machine retrofits—especially those replacing older Mavilor BL or Infranor CX motors—the Infranor Mavilor BLS-073 often fits existing mounts and couplings, offering a drop-in upgrade path to modern performance without mechanical redesign. Across all these uses, its compact 73 mm footprint saves valuable panel space while delivering industrial-grade reliability.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before mounting the Infranor Mavilor BLS-073, verify shaft alignment and coupling concentricity to avoid excessive radial loads (>150 N recommended max). Ensure the mounting surface is flat and clean per IEC 60034-14 standards. Use shielded, twisted-pair cables for power and encoder signals, with the shield grounded at the drive end only. Confirm that the servo drive’s bus voltage (typically 300–480 VDC) matches the motor’s rating, and never energize the motor without first configuring its feedback type and pole count.

Maintenance suggestions: The Infranor Mavilor BLS-073 is largely maintenance-free but should be inspected annually for signs of bearing wear (unusual noise, axial play), shaft seal integrity, and connector corrosion—especially in humid or corrosive atmospheres. Monitor drive-reported motor temperature; sustained operation above 85°C may indicate inadequate cooling or overload. If using with non-Infranor drives, validate torque limits and current scaling to prevent demagnetization. Never disassemble the encoder housing—this voids calibration and IP rating. Replace the Infranor Mavilor BLS-073 if vibration increases suddenly or if the absolute position resets unexpectedly after power cycling.
