10-3 Servo motors with reduction gears
Servo motors are available with reduction gears designed for: 1) general industrial machines; and
2) precision applications.
Servo motors with electromagnetic brakes are also available.
(1) Manufacturing range of servo motor with reduction gear
Servo motors with reduction gears that may be manufactured are indicated by symbols (G1 (H),
G2) in the following table. G1 (H) and G2 are symbols appended to the servo motor models.
(Refer to 2), (2) in Section 1-1.)
