Product Description:

The AKM2G-71P-ANJNCA00 is a servo motor manufactured by Kollmorgen within the AKM2G Magnetic Motors series. As a compact rotary actuator, it delivers precise torque and speed feedback to motion controllers, allowing coordinated movement in automated production cells, pick-and-place modules, and test stands. Its purpose is to convert regulated three-phase power into responsive mechanical shaft output suitable for high-performance industrial positioning tasks.

Electrically, the motor is rated for up to 400 VAC line supply and develops a continuous stall torque of 23.0 Nm while holding position without overheating. At its rated speed of 4900 rpm, the windings generate a back electromotive force of 73.3 Vrms/krpm, which is important for sizing the drive voltage margin. Torque rises in proportion to current with a constant of 1.10 Nm/Arms. Dynamic response is shaped by the q-axis inductance of 5.8 mH, which, together with the standard winding code P and the motor's 4 pole pairs, affects electrical time constants and ripple performance. Operation is allowed between 5 °C and 40 °C and at up to 95% relative humidity, supporting typical plant environments.

Mechanical interfaces follow an IEC flange with accuracy grade N; the bolt circle is 215 mm and the pilot diameter is 180 mm to align the 192 mm frame. A smooth 38 mm shaft transmits power, and rotor length code 1 keeps inertia moderate. Electrical termination uses an htec M40 connector sealed to IP65, while feedback is provided by an SFD3 single-turn device from Generation 3. The winding resistance of 0.274 Ohm and a thermal sensor set comprising PT-1000 plus PTC support protection functions. Heat soak is characterized by a thermal time constant of 38 minutes, so intermittent overloads can be tolerated. The motor is supplied without a holding brake.
