Product Description:

The SD-B4.140.030-10.000 is an electric magnet motor built by Bosch Rexroth Indramat for closed-loop servo axes. It converts electrical power into controlled rotary motion so actuators, conveyors, or tool spindles can follow precise velocity profiles in automated assembly, handling, and processing equipment. Because the stator windings are energized by an external drive, the motor fits multi-axis systems where compact dimensions and steady torque are important. This makes it suitable for motion systems that need repeatable speed regulation across changing load conditions.

The mounting interface uses a flange measuring 142 mm, allowing the frame to bolt directly to standardized machine plates. A solid shaft sized at 24 × 50 mm transmits load and supports alignment with couplings or gear stages. At standstill, the motor can deliver 14.0 Nm of torque, which is useful for indexing and tensioning tasks that require holding force before motion begins. Under rated excitation, it reaches a nominal speed of 3000 rpm, giving a balance between dynamic response and thermal loading. Magnetic excitation is produced with Ferrite, which provides stable flux characteristics and suits applications that require predictable operation.

The motor is supplied as basic equipment, so the output shaft is provided without a keyway. It also comes with no parking brake, which suits machines that already use external locking or holding methods. The absence of a brake also reduces rotor mass and avoids the extra wiring associated with brake release circuits. Classified as a Brushless servo motor, it uses electronic commutation to eliminate brush wear and reduce routine service needs. This arrangement helps maintain consistent torque production while allowing the external drive and feedback system to manage axis control.
