MDD041B-N-100-N2K-050GB1
The MDD041B-N-100-N2K-050GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for connection to digital drive controllers, where regulated current is converted into rotary motion for positioning axes, compact assembly stations, electronics pick-and-place heads, and small spindle systems. This operating role makes it suitable for applications that need accurate speed and position control during frequent starts, stops, and changes in direction. Its compact size and electrical interface also suit installations where high dynamic response is needed but available mounting space is limited.
Standard rotor balancing helps limit vibration during high-speed operation. The centering flange is machined to 50 mm so the motor seats accurately in matching machine interfaces, and it can provide a continuous standstill torque of 1.35 Nm without exceeding its thermal limit. Position data is supplied by an integrated absolute encoder, which allows the axis to reference position immediately after power-up. Under rated excitation, the rotor reaches 10000 rpm, which supports short-cycle motion in high-speed equipment. Closed-loop control also uses resolver feedback, giving noise-tolerant signal transmission in electrically harsh environments, while size code 041 and length code B help keep mass and inertia low.
Electrical terminations are oriented toward side B of the housing, which helps route cables through narrow machine spaces and keeps the rear connection layout compact. An integrated blocking brake provides 1.2 Nm of holding torque to secure the axis when power is removed, which is useful where gravity or external load forces could move the mechanism at standstill. The motor uses a plain shaft with a shaft seal, and the design omits an opposite-end extension to keep the overall length compact. Standard housing surfaces accept common flange patterns for direct installation in compatible assemblies.
