Product Description:

The G12A.DL80G4.CN07 synchronous servo motor is produced by KEB as part of the SM Synchronous Servo Motors series. This geared unit converts controlled electrical input from a drive into regulated mechanical output, pairing a permanent-magnet motor with an integral reduction stage. The integrated gear train lowers output speed and raises available shaft torque, which helps the assembly move loads that need steady low-speed motion. The design suits conveyors, pick-and-place heads, and similar automation axes that need stable speed and moderate backlash while occupying minimal installation space.

During continuous duty, the motor delivers 0.75 kW of shaft power at a nominal speed of 1400 rpm and draws a rated phase current of 1.98 A. Because the unit combines a servo section with a reduction stage, its steady-state output depends on both electromagnetic conversion and gearbox losses. Overall motor efficiency is limited to 75%, while the gear stage passes power with an efficiency factor of 0.96. The electrical section can accept as much as 1.5 kW of input from the inverter and operates with a displacement power factor of 0.73, which affects upstream power demand. A pull-out torque ratio of 2.3 allows short overload events before the rotor slips out of synchronism, giving the axis brief reserve capacity for upset loads.

Start-up conditions permit an inrush equal to a start current ratio of 4.7, producing a start torque ratio of 2.3 so the mechanism can overcome static friction without external assistance. Once motion is established, the gearbox tolerates up to 117 Nm of transmitted torque. A spring-applied brake on the secondary shaft is released by 24 V DC and supplies 15 Nm of holding torque to secure vertical or suspended loads. That brake can help prevent unwanted movement while the axis is stopped. The housing is rated IP54, which helps protect the motor in dusty production areas with occasional splashing water.
