Product Description:

The SF-A5.0250.020-10.015 is an electric drive element produced by Bosch Rexroth Indramat and assigned to the SF Servo Motors series. It converts inverter commands into controlled mechanical motion, so machine axes can follow precise speed and position references during packaging, assembly, or material-handling cycles. By integrating with the DC link supply of an Indramat drive, the unit works in a closed-loop arrangement that pairs feedback with torque production for repeatable performance across a broad operating range. This operating concept supports stable motion control in applications that require consistent acceleration, deceleration, and holding behavior during repeated machine cycles.

The stator windings are energized from a 670 V DC link, a voltage level that supports high power density without requiring larger conductors. A mounting flange of 190 mm centers the motor against machine plates, helping maintain alignment while transmitting radial loads. During startup or blockage, the unit can draw a locked-rotor current of 10 A, developing a stall capability of 23 Nm to overcome static friction. Once motion is established, it reaches a rated speed of 2000 rpm, balancing thermal behavior with dynamic response. Power reaches the terminals through a 4 x 1.5 mm² motor cable that mates with a 1.25 connector, which helps keep the electrical connection orderly and secure in compact installations.

The mechanical form factor includes a body length of 300 mm, which keeps installation depth manageable while leaving internal space for two NTC sensors that monitor temperature continuously. A mass of 24 kg provides useful rotational inertia while still allowing easier handling during installation. Shock resistance up to 6 g helps protect the magnet stack from impacts that can occur on indexing tables or shuttle drives. The electromagnetic design features a torque constant of 2.3 Nm/A, allowing the drive controller to match commanded current with predictable torque output. Continuous temperature supervision also helps the motor remain within its thermal operating range during repeated duty cycles.
