Product Description:

The Kollmorgen LSM215-451-204-M-2KA brushless servo motor is recognized by the part number M.1302.1381 and belongs to the LSM series. It is used in systems that require high power, accuracy and durability. This motor provides a constant torque of 51Nm and a peak torque of 158 Nm and is capable of running at 2000 RPM. It is also important to note that the torque constant Kt is equal to 1.84 Nm/Amp, and the voltage constant Ke is equal to 222 V/kRPM. The stall current is 29.7 A, and the maximum current is 106.1 A. The shaft is designed using ST 60 steel to provide high strength and rigidity.

Other aspects of this motor include maximum torque, which is 158 Nm or 1398 In-lb. Peak torque is the maximum value of the torque that can be generated by the motor for a limited time. It assists the machines in performing difficult operations efficiently and easily. Peak torque is crucial in any system that needs high force during startups or when the speed of the system needs to be changed. This makes the motor suitable for use in applications such as manufacturing, robotics or automation processes.

The motor also includes 8 poles. Poles are the magnetic devices which are present in the motor to determine the direction of rotation. The number of poles influences the motor's speed and torque. This type of motor comes equipped with 8 poles, which makes the rotative motion smoother and more stable, mainly at low speeds. Generally, more poles lead to increased control and higher torque values. This feature assists in enhancing the efficiency and precision of the motor in various motion control systems.
