RT3A 100x100

Product catalog summary

Mechanical Specifications
The rotary table RT3A 100x100 has dimensions of 143x110 mm and an overall height of 104 mm. It features a rotary plate with a diameter of 99 mm and a transmitted light aperture of 30 mm. The centering fits for the rotary plate and housing are Ø30H7 and Ø92H7, respectively. The radial run-out deviation is 4 µm, and the weight is 3.8 kg. It offers a positioning accuracy of 10 arcsec and a repeating accuracy of 2 arcsec. The mass moment of inertia for the rotor is 0.001 kgm², with a flatness of 4 µm. The allowable axial load is 1.7 kN, radial load is 1.2 kN, and tilting moment is 81 Nm. The maximum speed is 1300 rpm.

Protection Class
The device has a protection class of IP 40, with an option for IP 54 when blocking air is used.

Motor Data
The rotary table is driven by a directly driven rotary table with an electronically commutated 3-phase synchronous motor. The rated torque is 1.5 Nm (convection-cooled) and 2.5 Nm (water-cooled), with a rated current of 2.64 A. The peak torque for 3 seconds is 5.0 Nm, and the peak current is 8.8 A. The power loss at rated torque is 75 W. The electrical time constant is 1.19 ms, with an inductance of 12.8 mH and resistance of 10.8 Ω. The counter voltage constant is 4.99 V/1000 min⁻¹. The motor has 6 pole pairs and an allowable winding temperature of 60°C. The intermediate circuit voltage is 600 V.

Measurement System
The system uses a Renishaw SIGNUM measurement system with an external interface providing an analogue output signal of 1 V. An alternative digital output signal is available on request. It offers 11840 increments per rotation and includes an integrated reference mark.

Accessories and Connectors
The mounting kit includes 2 clamps, 4 hexagonal screws (DIN 933-M4x16-8.8), and 4 lock washers (DIN 127-B-4.1-A2). The motor connector has 4+4 pins, the measurement system connector has 17 pins, and the blocking air connector uses a push-in fitting QSM-M5-6-I. The connector for cooling is a push-in fitting QS-G1/8-6.
