Product Description:

The Kollmorgen M-803-B-A1-B3 is a brushless permanent magnet servo motor. It is suitable for use in industrial applications that require power and accuracy. This motor runs on 230V and has a maximum rotation speed of up to 2750 RPM, which increases its performance in automation systems. It has a stall current of DC-32.5 A (rms) and has the capability to draw a stall continuous torque of 0-41Nm, making it efficient for continuous use. This Servo Motor has an ingress protection of IP65; thus, it is safe from dust and water in industrial settings.

This motor's 129 Nm stall peak torque ensures smooth power delivery while handling load surges effectively. This high peak torque is useful in conditions where the motor needs to produce more force, for instance, when it has to move heavy loads or when accelerating to high speed. The 108.0A RMS stall peak current allows it to operate at high power for a short time in high-performance applications. It also has a back EMF constant of 80.6 V/KRPM and inductance of 16.3 mH, which enhances the electrical performance by reducing the energy wastage of the system.

This motor is built for high durability. It can effectively be used in continuous duty applications. It has a thermal time constant of 40 minutes, enabling it to work for a long time without overheating and, thus, is suitable for those applications that require high power output. Other features, such as its DC resistance of about 0.361 ohms at 25 degrees C and static friction torque of about 0.64 Nm, also ensure improved operations. This servo motor is strong and delivers high torque while weighing 36kg (79 lbs).
