Product Description

Kollmorgen is a global provider of motion equipment for original equipment manufacturers. Their products include industrial-grade high-performance motors, amplifiers, drives, and industrial PCs. The TBM series of frameless motors are one of the products that the company specializes in. These motors have low cogging designs, are RoHS compliant, and have banded rotors.

The TBM series is characterized by its performance, robustness, and reliability. The TBM-12941-A belongs to the TBM family of frameless motors. It has a motor frame size of 129 inches and a stack length of 41 inches. This motor has a cylindrical construction and has permanent magnets inside it. The TBM-12941-A must be mounted with a heatsink large enough to dissipate its heat rapidly. Overheating may damage the motor. This unit has a continuous stall torque of 8.30 Nm and a peak stall torque of 27.1 Nm. The TBM-12941-A is designed for a voltage of 100 V, and a peak current 57 A. This motor has a torque sensitively at 25˚C of 0.560 Nm/A. The max static friction for this unit is 0.346 Nm with viscous damping of 2.71E-01 Nm/kRPM.

The TBM-12941-A weighs roughly around 3.17 Kg and has 12 poles. This motor’s winding temperature can reach as high as 155˚C while the peak torques can be limited by lead wire gauge. This motor has various rotor hub geometries such as flat, hollow, round, flanged, and keyway. The TBM-12941-A also has a bolt hole diameter and circumferential pattern that can be adjusted according to the customer’s needs. The thermal sensors for this motor can be embedded in the motor slot only. The TBM-12941-A has a thermal resistance of 1.20˚C/Watt.
