Product Description:

The MSM215-319-304-S-2KA Servo Motor produced by Kollmorgen is developed for regulating motion-based operations in industrial automation systems. The servo motor functions at a velocity of 3000 rpm to generate 36 Nm torque continuously. During brief torques, this Servo Motor produces a maximum output of 100 Nm which exceeds its continuous torque of 36 Nm.

The MSM215-319-304-S-2KA servo motor delivers precise torque control through a rate of 1.36 Nm per amp because of its established design specifications. This motor supports voltage control in variable speed conditions through its defined voltage constant value of 164 V/KRPM. The motor exhibits six poles for establishing stable motion patterns. When operating in stall conditions the motor draws 28.7 amps peak before reaching its peak current level of 93.3 amps peak. The wire circuits between phases in this device reach 0.4 ohms when measured at room temperature 25°C. An operational specification of 10.6 mH determines the winding inductance to reduce electrical noise. With a rotor moment of inertia value of 0.0108 kg-m², the MSM215-319-304-S-2KA servo motor can achieve prompt speed changes. ST-60 steel components compose the shaft structure because they bring both additional durability and improved wear resistance properties.

The MSM215-319-304-S-2KA servo motor weighs 33 kg without the brake while the full version with the brake reaches a weight of 36 kg. These weights play a role in supporting installation-related mechanical design work. The selection of consistent drive systems depends on the electrical and thermal ratings information provided. This Servo Motor enables applications needing steady torque delivery as well as efficient speed adjustment together with speedy motion performance. The inertia rating climbs to 0.0138 kg-m² after brake installation because it enables accurate slowing operations.
