Product Overview
The LEVITRONIX BSM-4.1 / 100-10007 is a magnetically levitated (bearingless) brushless DC motor engineered for ultra-clean, high-purity fluid handling and precision rotary drive applications. Unlike conventional motors that rely on mechanical ball bearings, the BSM-4.1 utilizes active magnetic suspension to levitate the rotor within the stator bore, eliminating all mechanical contact, lubrication, and wear surfaces. This bearingless architecture makes the unit ideally suited for integration into centrifugal pump heads, where the motor rotor and impeller form a single rotating assembly suspended entirely by magnetic force. The result is zero particle generation, zero lubrication contamination, and exceptional rotational stability for critical industrial and life-science processes.

Engineering Features & Advantages
- Contact-Free Magnetic Levitation: The rotor is fully suspended by active magnetic bearings, eliminating mechanical friction, bearing wear, and the need for lubricants — ensuring an essentially unlimited service life in continuous duty.
- Zero Contamination Operation: With no mechanical bearings or seals in the drive path, the BSM-4.1 produces no wear particles and introduces no lubricant into the process fluid, making it ideal for high-purity and sterile applications.
- Integrated Pump Head Compatibility: Designed to accept a pump impeller directly on the levitated rotor, enabling a compact, seal-less centrifugal pump with a single moving part.
- Precise Speed and Position Control: Active magnetic control allows accurate regulation of rotor speed and position, supporting stable flow delivery and low-shear pumping of sensitive media.
- Direct Fit Replacement: Exact dimensional and functional compatibility with the original Levitronix BSM-4.1 platform and its associated controller ecosystem.
Typical Industrial Applications
The LEVITRONIX BSM-4.1 bearingless motor is deployed in applications where contamination-free, low-shear, and maintenance-free rotary drive is essential. Typical uses include semiconductor and electronics wet-process chemical delivery (CMP slurry and high-purity chemical pumping), pharmaceutical
