Rotary tables with direct drive series RT3 The rotary tables with direct drive are available in different types: RT3A100x100, RT3A100x155, RT3A80x130, RT3A150x100, RT3A150x130, RT3A250x170, RT3A150x60, RT3A200x60 und RT3G630x225 Rotary tables RT3G630 – high dynamics, high precision, high loading capacity This direct driven rotary table RT3G630 has particularly been developed for machine tool industry and assembly machines. It is characterised by its high precision, highdynamics and its high loading capacity. The rotary table is driven by a permanently excited 3-phase synchronous motor. The rotary plate and the housing are made of gray cast iron. To record the exact position and speed of the rotor and to commutate the motor an incremental measuring system with optical scanning has been integrated. Additionally to the seals, a blocking air connection offers protection against the permeation of dirt and humidity. Rotary table RT4A – high dynamics, high precision and extremly flat construction The rotary table RT4A400 is an exceptionally flat rotary table with air bearings. The rotary table housing and the rotary plate are made of aluminium. The integrated direct drive and its low overall height assure the realization of applications that cannot be performed with conventional worm drives. The drive principle also offers high accelerations and short cycle times.
