Product Description:

The AKM41S-ANS22-03 from Kollmorgen is part of their acclaimed AKM Synchronous Servo Motors series. It delivers exceptional torque from a compact design. This model supports applications that require reliable motor control, environmental protection, and operation in confined spaces.

The 2.1 N-m continuous stall torque of the AKM41S-ANS22-03 comes with a peak stall current of 22 Arms making it efficient for automation systems to overcome startup loads and inertia. The motor achieves precise positioning and rapid response times because of its 0.000059 kg-m² rotor inertia that ensures accurate control in operations. The motor’s performance characteristics perfectly suit robotics and packaging machinery as well as compact conveyor systems because they need precise control and dense torque capabilities. The motor displays an excellent capability of heat retention through its 17-minute thermal time constant which enables operational longevity even during lengthy cycles without thermal instability. The design guarantees steady temperatures and extended product lifespan throughout different stop and start procedures and variable load operations.

The IP54 protection class of this device enables resistance against dust and water spray which makes it practical for semi-protected areas including manufacturing lines and laboratory spaces and light industrial facilities. Its 70 mm diameter design provides compact dimensions so the motor can fit into systems requiring limited space. The Kollmorgen-made AKM41S-ANS22-03 features compatibility with many different drives and controllers which helps simplify the optimization process at the system level. This motor provides rapid control and high torque alongside excellent mechanical efficiency within a compact design which suits modernization of existing equipment as well as new system development. The AKM41S-ANS22-03 delivers an optimal selection for engineers because it combines a small package with powerful torque capacity and temperature-resistant construction.
