Product Description:

The SE-B2.040.060-10.015 belongs to the SE Synchronous Servo Motors series from Bosch Rexroth Indramat. It is a permanent-magnet servo unit intended for positioning and speed control tasks in industrial automation lines where rapid acceleration and compact envelope dimensions are required. By combining a 100 mm mounting flange with a shaft prepared for keyed couplings, the motor integrates easily with compact gearbox stages and belt drives common on pick-and-place axes and electronic assembly stations. This layout supports precise rotary motion in equipment where short travel cycles and limited installation space are both important.

An A-side flange sealed to IP67 keeps dust and coolant out of the stator cavity so the motor can be mounted directly on machining enclosures. The motor has a rated speed of 6000 rpm, while a standstill torque of 4.0 Nm supports holding duty or low-speed feed moves without an added brake. With a torque constant of 0.4 Nm/A, the drive amplifier must supply roughly 25 A for the motor’s peak torque range, while a standstill current of 10.0 A is sufficient to maintain rated stall output. The 100 mm flange and the 14 x 30 mm shaft provide a direct path for reaction forces into the machine frame. A winding resistance of 1.4 Ω and a voltage constant of 55 V/1000 rpm describe the back-EMF behavior that the inverter must overcome, and the overall mechanical length without a holding brake is 277 mm.

Dynamic behavior is characterized by an electrical time constant of 6.6 ms and a mechanical run-up time of 64 ms, allowing the load to reach commanded velocity quickly on high-speed stations. A rotor inertia of 0.75 × 10⁻³ kg·m² helps limit overshoot during rapid reversals, and the motor mass of 8.8 kg keeps cantilever loads low on moving gantries. The low inertia also helps the control loop respond quickly during short indexing moves and repeated direction changes. The thermal time constant is 25 minutes, which supports moderate duty cycling before derating is needed.
