RACO DCLM Series Rod-less DC Motor Driven via a precision Gearhead, Electric Linear Actuators

DCLM - When Economy is the Primary Requirement

The RACO DCLM is the economical system solution for linear motion applications that do not require the high performance, closed loop precision of a brush-less servo actuator. Each of the DCLM system models feature a brush type DC gear motor with a performance matched regenerative motor driver to provide linear motion with a package price approximately one-half that of a servo mechanism of equivalent stroke length. The performance envelope of the DCLM family ranges from the high speed 3A unit (55"/sec. 35 lbs. load; 45 lbs. thrust) to the high load 4C unit (12"/sec. 600 lbs. load; 200 lbs. thrust). The DCLM linear motion mechanical elements are identical to those of RACO‘s SLM premium performance servo actuator system.
