Product Description:
The 8LSA46.DB030S100-3 is a B & R Automation's manufactured synchronous motor, which is an efficient and compact motion control solution for precision motion control. This motor has a nominal power output of 2419 W and can be used in applications requiring smooth and reliable torque output.
This 8LSA46.DB030S100-3 motor consumes a nominal current of 4.7 A without sacrificing torque or speed performance while ensuring low energy consumption. This motor features a stall torque of 10 Nm to hold force when under static load conditions. This synchronous motor has a maximum speed of 12000 rpm to facilitate operations that demand speedy and responsive movement cycles. The torque constant of 1.63 Nm/A allows smooth torque delivery by this motor. This motor’s voltage constant of 98.44 V/1000 rpm ensures efficient back EMF that maximizes the dynamic performance at different speeds. This motor’s thermal time constant is 40 minutes with sufficient thermal stability to perform long-duration operations under continuous duty. The value of the moment of inertia for this synchronous motor is 4.387 kg·cm², and this brake-free motor weighs 7.3 kg, leading to minimum system load and easy application in tight mechanical structures.
For electric interfacing, this 8LSA46.DB030S100-3 motor accommodates a cross section of 0.75 mm² for B&R motor cable to ensure effective transmission of current and thermal protection along the cable length. The connection type of the 8LSA46.DB030S100-3 motor is a single-cable solution that combines power and signal transmission to ease wiring and installation time. The direction of connection is swivel-based on the SCS standard to allow mechanical flexibility while assembling and maintaining the system. The 8LSA46.DB030S100-3 synchronous motor incorporates a 32-line multi-turn encoder, which is designated as DB 2.2 inductive, providing high-resolution feedback with multi-turn capability for precise absolute positioning.
