Product Description:

The SE-B4.210.050-10.015 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. This rotor-stator assembly is intended for closed-loop industrial axes where quick speed changes and accurate torque response are required, such as pick-and-place gantries, packaging spindles, and electronic cam followers. By converting three-phase drive current into regulated mechanical rotation, the unit delivers programmable motion that can be coordinated with PLC or CNC controllers across a wide operating load range.

Its nominal shaft velocity reaches 5000 rpm, allowing high surface speeds for tooling or conveyor segments. Acceleration is aided by a ramp-up time to rated speed of only 60 ms, which minimizes dead time between production cycles. When rotation is halted, the motor can sustain a static torque of 18 Nm, providing position-holding capability for indexing tables or vertical loads. The electromagnetic conversion efficiency is reflected in a torque constant of 0.64 Nm/A, so each ampere delivered by the drive produces roughly two-thirds of a newton-meter at the shaft. During standstill at maximum continuous torque, phase conductors carry 28 A, a current level that sets the thermal load on cabling and drive components.

Short-term overload demands are handled by a maximum torque of 52.0 Nm, while the inverter may supply up to 174 A of peak current without exceeding magnet or winding saturation. Back EMF scales with speed according to a voltage constant of 68 V/1000 rpm, and the drive uses this value for field-oriented control and commutation angle calculation. The laminated core, windings, and housing weigh 22.0 kg, a mass that affects mounting hardware selection and contributes to the motor’s inertial characteristics during rapid reversals.
