Product Description:

The MSM215-407-304-S-0KA Brushless servo motor is made by Kollmorgen. The servo motor is a Kollmorgen servo motor that can be utilized for accurate power and speed control. The MSM motor is designed for tasks that must be completed consistently and is compatible with automated motion systems.

The motor gives off a steady 40.6 Nm of torque, which works for tasks that need a stable torque output. Since it has a peak power of 133.6 Nm, it can handle short periods of heavy loads. The servo motor can handle a constant torque of 28.7 A, which is the same as its stall current rating. The motor can keep delivering torque even when the load changes because the highest peak current is 64.4 A. When the voltage output is divided by the rotational speed, the voltage constant KE becomes 170 V/krpm. The torque constant, KT, is 1.4 Nm/A, which links the amount of torque produced to the amount of current applied. Its electrical qualities are determined by the 0.28 Ohm winding resistance between stages. The windings' 6.0 mH inductance contributes to the motor's consistent electrical time.

The motor's body length is 463 mm, which allows it to be installed in systems that have clear room needs. The is designed to withstand mechanical stress from repetitive tasks that require consistent power output. The electrical components are configured so that they generate the least amount of heat possible, which helps in long-term reliability. The KE and KT figures are set to their maximum values to ensure that the voltage and current are suitable for the torque requirements. The MSM215 servo motor is designed to deal with applications that require repeatable precision placement.
