ASB59: compact absolute encoder with taper solid shaft Core of the elevator system is the motor used to raise and lower the elevator car. Gearless traction motor technology has brought about rapid changes within the elevator industry. A few reasons for its increased popularity include the ability of longer travels up to the tallest buildings; higher mechanical and electrical efficiency; elimination of parts and thus reduced physical size that allows for smaller machine room or machine-room-less (MRL) installations; and low overall maintenance. Encoders for gearless motors are sturdy, reliable, accurate; furthermore, especially in MRL installations, they must be really compact. ASB59 is the new absolute encoder developed for reliable speed and position feedback on gearless motors. It features a space-saving and flat design (42-mm only low profile) with compact 58-mm flange diameter housing in both solid and hollow shaft configurations. Along with the 12.7- and 15-mm blind hollow shaft Lika Electronic exhibits the model with 10-mm diameter 1:10 taper shaft for absolutely backlash-free and torsionally rigid mating. Furthermore it is claimed to provide a variety of simple and quick yet sturdy coupling solutions by means of front and rear fixing plates for maximum safety and minimum time loss. Resolution up to 17 bits allows very accurate detection of the rotor/stator position. ASB59 is offered with SSI and fully digital BISS-C interface.
