Product Description:
The 8LSA55E2030D200-0 is a 3-phase Synchronous servo motor from the 8LS series of B&R. The servo motor is equipped with a connector housing that is designed to facilitate self-cooling. The motor is designed for applications that require a compact form factor and moderate torque.
The 8LSA55E2030D200-0 synchronous servo motor is equipped with an EnDat 2.2 single-turn inductive encoder (E2), which guarantees precise digital feedback for closed-loop control. It uses a hybrid single-cable connection system with angled connections and has a nominal speed of 3000 RPM. The D2 motor option configuration features a holding brake and a keyed shaft. The model uses version 0 of the motor design, and the construction type is standard with no additional options. The motor produces a nominal torque of 11.6 Nm and an equivalent nominal current of 7.1 A. The servo motor produces a nominal mechanical output power of 3644 W. The motor can operate at a maximum speed of 9000 rpm. The stable dynamics of current control are facilitated by the electrical time constant of 11.1 milliseconds.
The voltage constant is 98.44 V per 1000 rpm, while the torque constant is 1.63 Nm per ampere. The stator inductance is 12.5 millihenries, and the stator resistance is 1.127 Ohms. For heat dissipation, the thermal specification includes a thermal time constant of 40 minutes. The 8LSA55E2030D200-0 servo motor weighs approximately 10.4 kg without the brake, and the rotor has a moment of inertia of 8.19 kg·cm². The holding brake has a brake mass of 1.5 kg and an additional inertia of 1.66 kg·cm², resulting in a braking torque of 15 Nm. The motor frame is optimized for efficient heat transfer, and the cooling method is passive (self-cooled).
