Product Description:

The MSM215-407-304-S-2KA is a Brushless servo motor that was created and made by Kollmorgen. The servo motor is made to meet the exact motion control needs of many different robotic systems.

The MSM215-407-304-S-2KA servo motor provides a constant torque of 40.6 Nm and a maximum torque of 133.6 Nm. The motor's stall current is 28.7 A, while its peak current is 64.4 A. KT stands for torque constant (1.4 Nm/A), and KE represents for voltage constant (170 V/krpm). The coil resistance, measured from phase to phase, is 0.28 Ohms, allowing energy to reach its destination rapidly. The coil inductance is 6.0 mH, allowing for the production of a magnetic field with reliability. The rotor shape and choice of materials balance the thermal and dynamic properties, which makes the system reliable. The MSM215's rotor has 0.00795 kg·m² of inertia, allowing for regulated acceleration and deceleration. The motor body measures 463 mm in length, making it easy to position and integrate into both small and large motor assemblies.

The MSM215-407-304-S-2KA servo motor works with electrical features that make it quicker and better at handling loads. The electrical properties are in sync with the torque creation to make sure that the torque stays the same even when the load changes. The servo motor has mechanical specs that make it work with a number of different drive methods. The motor's low winding resistance and small inductance allow it to respond fast to control signals. The servo motor is designed for applications requiring accurate positioning and a consistent rotational force. The torque constant allows the torque production to develop linearly with the current. This makes it easier to adjust motion.
