Utilising high energy rare earth magnet material, the M4-295X series DC servo-motor-tach units provide precise motion control in machine tools, robotics, automatic material handling, wiredrawing, paper, plastic-film and foil processing, tension controls and packaging machinery. Peak torque of up to 40 Nm gives ample power for fast, accurate positioning. Coupled with low motor inertia, theoretical acceleration of up to 25,000 rad/sec2 results.
With a speed range capability in excess of 20,000 : 1, one motor can provide rapid traverse and feed rates for each machine axis, eliminating the complexity and compliance of multiple motors, clutches, and gear trains. Speeds as low as 6 revs. per hour may be achieved in a position loop without cogging. The unique permanent-magnet structure eliminates thermal runaway and commutation problems commonly encountered in conventional ceramic-magnet motors.
