Motor Mounting Styles
The ER Series Rodless Actuator includes pre-mounted DC stepper, brushless servo or brush motors. Motors may
be mounted inline, or directly coupled to the screw shaft (screw drive) or pulley shaft (belt drive). Alternatively, motor
may be mounted in a variety of parallel (or reverse-parallel) configurations. Parallel mounting link the motorshaft and
actuator drive shaft through a timing belt and pulley system. Refer to the model code pages (pp. 6-7) and Catalog
1894, Electromechanical Actuator Products, for a detailed description of the many mounting possibilities. Each
motor mounting assembly may be applied to all ER Series types: screw and belt drive, roller bearing and square rail.
