Product Description
Bosch Rexroth’s cost-effective, rapid-response automation systems are formed when Indramat drive controllers are combined with digital AC servo motors. A class of these servo motors is the MDD series of synchronous motors. The motors in this series vary in size, speed, and torque but have shared advantages, including high power-to-weight ratio and synchronous operation features. They are used in robotics and handling machines.
The MDD090A-N-030-N2M-110PB1 is one of the servo motors in Bosch Rexroth’s MDD series. It has low inertia thanks to the use of iron oxide and rare earth materials in the construction of its rotor’s permanent magnets. Another benefit is that it has a torque-inertia ratio that favors high dynamics. The motor has a brushless design and lifetime-lubricated bearings that support high radial loads. Hence, the direct mounting of pinions and belt pulleys is allowed. It is also equipped with thermal sensors in its windings to monitor its temperature and prevent damage due to overload. Its cooling methods are natural convection and surface cooling.
Electronic commutation in the MDD090A-N-030-N2M-110PB1 gives it a high cyclic load capacity which is ideal for continuous start-stop operations with high repetition rates. Its nominal speed is 3,000 revolutions per minute, while the moment of inertia of its rotor is 20 x 10-4 kgm2. The motor’s position is detected using digital servo feedback with an integrated multiturn absolute encoder. Using the optical measuring principle, it achieves impressive precision and has a system accuracy of ±0.5 angular minutes. There is also a blocking brake with a torque of 6.5Nm in this motor, and it ensures the backlash-free holding of the servo axis when no power is supplied.
