Product Description:
The SE-B3.075.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is designed for compact machine axes where digital drives require rapid, repeatable rotary motion. In automated pick-and-place modules, carton formers, or high-speed spindles, the motor converts commanded current into tightly regulated torque so that position loops remain accurate during rapid cycle changes common to industrial automation.
A nominal shaft speed of 6000 rpm establishes the continuous operating speed available from the motor when it is paired with a compatible drive. Transient load spikes are supported by a peak current of 84 A, giving the control system additional capacity for acceleration and disturbance rejection. At standstill, the motor can sustain a continuous torque of 8.2 Nm while remaining within its thermal limits. The electromagnetic design provides a torque constant of 0.58 Nm/A, which allows the controller to convert phase-current commands into the corresponding mechanical torque. The phase winding resistance is 0.90 ohm, and this resistance contributes to copper losses while affecting the voltage required from the drive.
A peak torque of 22.0 Nm is available for short intervals, allowing the axis to overcome high inertia or temporary process friction without stalling. The motor has a mechanical time constant of 59 ms, supporting quick changes in speed when sufficient drive current is available. Its thermal response is characterized by a thermal time constant of 25 min, which indicates how quickly the winding temperature approaches a steady operating level under a constant load. The back electromotive force constant is 63 V/1000 rpm, indicating how much voltage the rotating motor generates in proportion to shaft speed and helping the drive manage high-speed operation and regenerative deceleration.
