Kollmorgen has announced the new TBM2G series of frameless servomotors, introducing features that simplify the design of collaborative, surgical, aerospace and defense and other robots while delivering optimal performance in a lighter, more compact package. These new motors will complement Kollmorgen’s existing TBM and KBM series of frameless motors.Â
Three-dimensional finite element analysis (FEA) simulation and research from published information is used to compare the features of various coil configurations.
These versatile, low-cost and high-torque motors may be used open loop or as full servos - and several levels in between. The motor stator laminate designs divide these motors into those optimized for full stepping, and those optimized for micro stepping and servo operation. These differences can be easily measured with basic meters and oscilloscopes. Motor to motor variations can also be easily measured, and motor inductance at nominal speed and current can also be determined.
