Product Description:
The B & R Automation’s synchronous motor, with a product code 8LSAA4.EE045FFGG-3 is designed to offer high precision and efficiency in industrial applications that demand continuous power delivery. This synchronous motor has a nominal speed of 4500 rpm to provide smooth and precise motion.
This 8LSAA4.EE045FFGG-3 motor is designed to perform challenging tasks with a nominal power output of 1319 W, which makes it suitable for applications that demand reliable and continuous power. This motor provides a nominal torque of 2.8 Nm, which is essential for steady rotation applications. Under heavy loads, this synchronous motor provides a stall torque of 3.2 Nm, ensuring it can tolerate momentary load spikes without stalling. This motor's torque constant of 0.97 Nm/A determines how efficiently it can convert electrical power into mechanical torque to deliver a balanced and efficient performance in diverse applications. Designed as highly efficient, this motor has a stator resistance of 5.3 Ω and stator inductance of 12.4 mH to keep electrical losses low and contribute to stable operation. The stall current of this motor at 3.3 A is an important parameter since it restricts the maximum current draw during overload to prevent overheating and electrical damage. The maximum winding temperature of this synchronous motor is 155°C, and it can handle high thermal loads without compromising efficiency.
This motor also withstands a maximum flange temperature of 65°C to provide additional flexibility in operating environments where heat is an issue. The 8LSAA4.EE045FFGG-3 synchronous motor has five pole pairs to make it an ideal option for high-accuracy industrial operations needing a consistent power supply for long periods. For storage purposes, the 8LSAA4.EE045FFGG-3 motor can withstand temperatures ranging from -20°C to +60°C, and the relative humidity should be less than 90%, non-condensing, to maintain its internal components’ integrity.
