Video: RIB Torque Motors Stand For More Productivity, Quality And Precision
INA - Drives & Mechatronics AG & Co. KG (IDAM) focused on the torque drives of the RIB series at the autumn trade fairs in 2016. The optimized heat transfer resistances in these torque drives should not only lead to a significantly cooler motor, but also to a thermally more stable system and thus to more quality and precision. Compared to the previous RI series, the RIB torque motors can be operated with up to 20% more maximum torque depending on the operating strategy (design strategy "torque-optimized motor") or due to lower capacity utilization at the same operating point with 30% less heat loss (design strategy "loss-optimized motor").
Torque-optimized or loss-optimized motor
The "torque-optimized motor" variant is suitable for large-scale production where the axis (drive) to be designed is a bottleneck in production and limits the performance of the production line. For the manufacturing process, the drives are designed in such a way that the installation space is used to the maximum and the highest drive power that is reasonable for the process is installed. With the "loss-optimized motor", however, the drive is deliberately oversized. The engine temperature or the heat loss power of the engine is significantly lower during operation and the system accuracy increases. As a result, surface quality and dimensional accuracy increase. However, the “oversizing” usually results in a slightly higher price.
Energy-efficient and economical - new torque motors from Schaeffler
In terms of design, the additional costs should be partially compensated for by adapting the active magnet length to the application and making optimal use of the installation space. The motors of the RIB series are available from IDAM as built-in motors consisting of a rotor and stator or as complete drives (rotary tables).
High-end drives for productronic and robotics
The RIB motors should be suitable as complete drives, due to their high dynamics and high control quality for extremely dynamic movements and precise positioning, as are common in automation and productronic. Current developments also show the potential of RIB motors as direct drives in robot arms. According to IDAM, their high accelerations and precise positioning make them ideal for use in the hand axes of articulated arm robots. (sh)
