Operating at speeds up to 240 ips, cog-free BLS Series is intended for long-stroke, high-speed, closed-loop applications. Iron-core BLD Series, with forces of more than 500 lb continuous, is designed for long-stroke, high-force, closed-loop applications. Both are available with motor coils featuring Hall-effect assemblies for trapezoidal commutation, or without Hall effects if used with linear encoder and commutation is achieved through software.
