TBM2G: FRAMELESS DIRECT DRIVE TORQUE MOTORS WITH HOLLOW SHAFT FOR LOW VOLTAGES 48VDC / 24VDC AND BELOW - DESIGNED FOR ROBOTIC JOINTS
Description
Kollmorgen introduces the new TBM2G series of frameless torque motors with hollow shaft specifically designed to optimise the design of collaborative and medical robots, aerospace and defence robots and other robots. The TBM2G servo motors are the evolution of the existing TBM and KBM motor series according to feedback from our customers - the TBM2G motor series represents the result of several years of research and development and testing and, with its hollow shaft and optimised windings, simultaneously enables optimal performance in a lighter, more compact package and high performance torque through an extremely compact electromagnetic design. These next-generation torque motors enable the design of robots with lower joint weight, higher load capacity, improved energy efficiency, reduced thermal input and more dynamic movements.
The TBM2G are ideally suited for battery-powered and mobile applications such as autonomous mobile robots (AMR) and automated guided vehicles (AGV). The seven frame sizes correspond to the sizes used in embedded applications such as collaborative and surgical robots. The standard sizing is optimised for combination with commercially available shaft gearboxes. The large inner diameter through hole of the TBM2G hollow shaft motors can be used for encoders, cables, hoses, shafts, tools, etc.
The main features of the TBM2G torque motor series are:
- seven sizes from 50 to 119mm outer diameter
- hollow shaft from 24.75 to 57.5mm
- optimised standard windings for 48V (DC) / 24V (DC) and below
- optimised windings for speed and torque requirements in collaborative robot applications weighing 3.5 and 15 kilograms and more
- multiple standard thermal sensor options to suit the most popular drives on the cobot market
- low cogging torque for smooth operation
- optional integrated Hall sensors that do not extend the motor length
- designed to perform well without exceeding 85 °C, but at the same time capable of delivering full
capable of maintaining full power at winding temperatures up to 155 °C on a continuous basis - corrosion-resistant stainless steel rotors with hollow shaft
- epoxy-coated ring magnet (neodymium, NdFeB)
- optional: connectors and customised versions (Kollmorgen Co-Engineering)
