Product Description:
The MSM165-146-304-S-0KA is a 3-phase synchronous servo motor from Kollmorgen, a well-known industrial automation company. This is part of their IndraDyn S series and is for high-performance applications. It runs at 230V, standard industrial power supply and 2 HP, so it’s power output. The 6-pole design is important for speed and torque characteristics. The number of poles determines the synchronous speed, and the drive frequency determines the rotational speed. With six poles and 3000 rpm max speed it’s a specific drive frequency. It’s for use with frequency inverter drives, which allow you to control speed and torque by varying the frequency and voltage of the motor windings. This is important in automation, where variable speed and positioning are required. The winding inductance is 6.6 mH. Inductance plays a big role in the motor’s electrical behavior; it affects the current flow and the motor’s response to voltage changes.
A higher inductance can limit the rate of current change and affect the motor’s dynamic performance. Rotor inertia is 0.0036 kg-m², it’s a measure of the rotor’s resistance to speed changes. Lower inertia is generally good for applications that require fast acceleration and deceleration; it allows the motor to respond quicker to control signals. The torque constant (KT) is 1.34 Nm/Amp, it’s the motor’s efficiency in converting electrical current to mechanical torque. A higher torque constant means the motor can produce more torque for a given current, which is important for demanding applications. The voltage constant (KE) is 95 V/KRPM, also known as the back-EMF constant; it relates the motor’s speed to the voltage across its terminals. This is important for drive control and for understanding the motor’s behavior during regenerative braking. Weight is 12.0 kg.
Peak current 40.1 amps, this is the maximum current the motor can handle without damage. This is important for drive sizing and ensures reliable operation under peak load. Winding resistance of 0.4 ohms (phase to phase at 25°C) is the opposition to current flow within the motor windings. This affects the motor’s efficiency and temperature rise. Lower resistance means higher efficiency and less heat generation. Stall current 123 amps peak is the current that would flow through the motor windings if the rotor is held stationary and the rated voltage is applied. This is important for drive sizing and protection; this is the maximum current the drive must be able to handle.
