MAD100D-0250-SA-S2-EP0-05-N1

The Bosch Rexroth Indramat MAD100D-0250-SA-S2-EP0-05-N1 is a high-performance spindle motor in the MAD IndraDyn A Motors series, designed for precision industrial applications. Manufactured by Bosch Rexroth Indramat, this motor combines robust construction with advanced feedback technology to deliver consistent torque and reliable operation. Featuring a flange mounting style and standard bearing arrangement, it integrates seamlessly into a wide range of mechanical assemblies. The motor’s singleturn absolute encoder provides high-resolution position feedback, ensuring precise control and rapid response in demanding environments. With an axial fan cooling mode, the MAD100D-0250-SA-S2-EP0-05-N1 maintains optimal thermal performance under continuous load.

This servo motor is defined by detailed technical specifications that ensure predictable performance. It employs a Winding Code 0250 with a rated torque of 50 Nm and operates on a connecting voltage of 3 x 400V. The rated current is 32.4 A, while power usage is 100 VA, and the total mass is 72 kg. The motor frame measures size 100 and length D, corresponding to a physical dimension of size 130. It is built without a holding brake and features a Shaft Type: whole-key balanced with shaft seal for smooth power transmission. Vibration resistance is specified by Vibration Grade R, ensuring stability in high-speed rotations. Additional core specifications include the Encoder Type: Singleturn absolute encoder EnDat 2.1 and a Connection Side: A-Side for straightforward cabling.

Operationally, the MAD100D-0250-SA-S2-EP0-05-N1 excels in applications requiring steady rotational performance. Its axial fan (propeller-style) cooling system moves air parallel to the shaft axis, maintaining thermal time constant of 30 minutes for prolonged duty cycles. The motor achieves a rated speed of 2000 rpm and incorporates 3 pole pairs for stable torque generation across the speed range. Built to an IP65 protection class, it resists dust and water ingress in challenging factory environments. Without a holding brake, the motor relies on controlled deceleration routines to manage inertial loads safely.

Designed for seamless system integration, the MAD100D-0250-SA-S2-EP0-05-N1 interfaces directly with industrial drive controllers and converters from Bosch Rexroth Indramat. Its flange mounting and standard bearing architecture simplify mechanical alignment in CNC machine tools, packaging systems, and assembly lines. The absolute encoder eliminates homing procedures and reduces commissioning time in automation setups. Target applications include precision machining centers, robotic joints, and high-accuracy positioning systems where reliability, accuracy, and continuous operation are critical.
