Product Description:
The U12M4T servodisc motor built by Kollmorgen , functions with precise electrical and mechanical characteristics by exhibiting low torque ripple due to its cogging-free design. Kollmorgen company stands out by supplying technological products that are regarded in various industries.
The U12M4T servodisc motor runs fast at a nominal speed of 3000 revs per minute with a peak torque of 852 N·cm and a continuous torque that is rated at 81 N·cm measured at 25°C. The maximum speed reaches up to 6000 RPM to make it efficient in industrial automation. The motor exhibits zero cogging torque which aids in continuing stable operation. The rated terminal voltage is 40.4 volts with a continuous current of 8.71 amps and a peak current of 85 amps. Its winding specifications show a terminal resistance of 0.750 ohms and an armature resistance of 0.610 ohms. The back EMF constant is rated at 10.60 V/KRPM to support its electromotive force function. This series ServoDisc DC motor’s viscous damping constant is 2.0 oz-in/KRPM and the desired armature inductance is noted to be under 100 microhenries which provides useful information for controlling the motor accurately in various systems.
The U12M4T servodisc motor has a moment of inertia of 0.0260 oz-in·sec² which affects how quickly it can accelerate or decelerate. The average friction torque is 6.0 oz-in or 4.2 N·cm and the unit weighs merely 3.6 kg with a diameter of 5.50 inches and a length of 2.11 inches which shows its sturdy structure. This compact design allows for integration into moderate-sized systems where space is a consideration. The power output is 254 watts which aids in offering steady performance without excessive heat generation.
