Comparison of rotary motor and Linearstep when using linear guide

By changing the rotary motor to linear motor, cost reduction can be expected by reducing the number of parts such as bearings and couplings and reducing the design and installation man-hours.
It is also advantageous for securing space because it is compact.
We recommend our "Linearstep Series" for the work linear motion part.

Number	Parts	Rotary motor	Linear motor
①	Lead screw	〇	×
②	Gear	〇	×
③	Bearing	〇	×
④	C type retaining ring	〇	×
⑤	Bearing plate	〇	×

Using a linear motor eliminates the need for the five parts (① to ⑤) used in a rotary motor.

PM captive type (built-in captive type)

Since the PM captive type has a built-in captive mechanism inside the motor, mechanical parts such as guides can be reduced.
