Product Description:

The SD-B4.092.020-00 is a servo motor manufactured by Bosch Rexroth Indramat in the SD Magnet Motors series. Within an automated axis, it converts commanded electrical current into rotary motion and feedback-driven torque so machinery can position loads precisely at moderate speeds. It is suited for indexing tables, packaging spindles, and light material-handling arms that require consistent speed regulation and repeatable positioning accuracy. Because the motor operates in a closed control loop, it can correct speed and position changes as the driven load varies during motion.

An external flange diameter of 142 mm sets the mounting interface for gearboxes or direct-drive couplings and provides a broad contact surface at the machine face. The rotor uses Ferrite magnets, a ceramic material that provides stable magnetic flux without rare-earth elements. Under rated conditions, the shaft reaches 2000 rpm, which supports smooth velocity control in moderate-speed motion systems. When stationary, the motor can produce 9.2 Nm of holding torque while current is applied, helping the axis resist movement at standstill. Mechanical power is transmitted through a shaft with keyway and featherkey, which provides a positive connection to pulleys or couplings and helps prevent slippage during acceleration.

As a Brushless servo motor, it uses permanent-magnet excitation and electronic commutation to avoid brush wear during operation. Coupling dimensions are based on a ø 24×50 mm shaft journal, which matches standard industrial hubs and supports accurate alignment at the driven connection. This shaft format works with the keyed output to transmit torque through common couplings, pulleys, or hub-mounted elements. The output proportions also help the motor fit standard transmission components without requiring oversized shaft hardware.
