Autonics AK-G Series Geared type 5 - Phase Stepper Motor

42mm Square, Shaft Type, 1.2A/Phase, 2.06 kgf-cm Torque
Compact and lightweight with high speed, high accuracy, and high torque
Space-saving design ideal for building compact-sized systems
Low, economical prices for improved cost efficiency

The shaft type 5-phase stepper motors AK Series, deliver reliable performance at low costs. The motors will satisfy users looking for motors with high precision, speed, and torque. The AK-G Series are geared shaft type stepper motors which offer higher torque from compact sizes and flexible angular control.

These dimensions are for dual shaft models. Single shaft models do not include shafts indicated in the dotted lines.
For flexible coupling (ERB Series) information, refer to F-64. (frame size 60mm, 80mm: Geared type, Geared+Built-in brake type)
Brake is non-polar and be sure to observe rated excitation voltage (24VDC).
SW1 ON : Brake Release / SW1 OFF : Brake Execute

Frame Size 42mm

Application model: Geared type, Geared+Built-in brake type, Rotary actuator type, Rotary actuator+Built-in brake type
