The product at hand is the Bosch Rexroth R911247504 (MDD093B-N-030-N2L-110GB0), a servo motor designed for digital drive controllers. This motor belongs to the MDD series, a collection of nine distinct motors designed to cater to different torque and speed requirements. The R911247504 (MDD093B-N-030-N2L-110GB0) model is particularly suitable for dynamic applications including roller feeds and tool changing devices. It is a permanent magnet synchronous motor with electronic commutation, which ensures reliable, maintenance-free operation. This model operates at a nominal speed of 3000 RPM and has a standard-housing design fit for either natural convection or surface cooling. It generates continuous torque and current of 14.5 Nm and 24.1 Amps with natural convection, and 20 Nm and 33.2 Amps with surface cooling. The motor is void of a blocking brake, and its weight is 16.5 kilograms. Furthermore, the motor is protected with an IP65 rating.
