R911256235
The R911256235 (MDD093B-N-020-N2L-110PB2) is a digitally commutated synchronous motor from Bosch Rexroth's MDD line. Known for its extensive functionality and versatility, this motor is often utilized in conjunction with Indramat's intelligent digital drive controllers to create efficient and responsive automation systems. This model is particularly ideal for high dynamic operations in pressing, punching, and nibbling machines due to its high power density. Additional features include an integrated digital servo feedback system for relative indirect position evaluation, shaft with keyway for form-fitting shaft-hub-connections, and a 22.0Nm blocking brake for holding servo axes when disconnected from power.
The standard housing design of the R911256235 (MDD093B-N-020-N2L-110PB2) allows cooling by natural convection and provides high overload capability due to its efficient heat conduction. Its completely sealed enclosure makes it resistant to damage from coolants or emulsions and allows for usage within machine working areas. Along with an IP 65 protection rating, the motor is safe from external object penetration and water sprays. An internal thermal sensor prevents damage from potentially harmful temperatures. The motor performs optimally between 0°C and 40°C and can function at a maximum relative humidity of 95%. Installation should not exceed a maximum height of 1000m.
