Product Description:

The MDD093B-N-020-N2L-130PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into precise rotary motion for positioning tables, feed axes, and automated tooling. The motor is intended for controlled industrial axes where the drive must respond quickly to command changes and keep motion repeatable from cycle to cycle. Its 093 frame designation fits mid-range machinery, and the B length code sets the overall depth for motor bays with matching space. The motor also uses a standard housing and standard dynamic balancing for regular industrial duty.

The motor develops a continuous standstill torque of 14.5 Nm, allowing steady holding force on static loads without thermal overload. Under rated excitation, it reaches a nominal speed of 2000 rpm for speed-controlled processes. Power and feedback conductors exit on side B, and the electrical interface uses a keyed connector for the cable connection. Precise mechanical centering is provided by a 130 mm centering diameter, which helps align the motor to the machine frame. Cooling is done by air convection across the ribbed housing, and a shaft seal helps block coolant or lubricant ingress during normal operation.

The motor uses digital servo feedback (DSF), supplying high-resolution positional data to the controller for tight velocity loops. This feedback arrangement supports accurate speed regulation and position tracking during continuous machine cycles. For applications that rely on external brakes or gravity-neutral axes, the motor is supplied without a blocking brake. The output uses a keyway shaft for positive torque transmission to couplings. It also has single-ended output, so the rear remains closed instead of using a shaft extension on side B.
