Product Description:
The 8LWA22.B9045S200-0 servo motor is produced by B&R Automation and belongs to the 8LWA High Torque Servo Motors series. Designed for industrial automation, this high-torque actuator provides closed-loop position and velocity control on packaging lines, assembly stations, and material-handling axes. It replaces pneumatic cylinders when electronic coordination is needed, and its smooth shaft couples directly to gearheads or pulleys without keys. The device’s compact frame supports dense multi-axis layouts inside cabinets or on moving carriages.
Electrical and mechanical interfaces aim at simple installation. The power, signal, and brake leads exit through an angled swivel connector that supports the single-cable approach, so only one hybrid line must be routed through drag chains. Internal heat is removed by self-cooling, avoiding external fans. Under rated conditions, the rotor reaches 4500 rpm, while an integrated brake holds up to 2.2 Nm at standstill. Position data moves over the EnDat 2.2 protocol, and the housing is sealed to IP64 against dust and spray. A smooth shaft, motor size 2, and length code 2 keep the envelope small, and the absence of an oil seal minimizes friction in dry environments.
Feedback accuracy is provided by a multi-turn encoder that produces 19/12 bits of resolution per revolution and stores 4,096 turns, while cumulative error is limited to +120 arcminutes. This precision supports synchronized groups where positional drift cannot accumulate. Mechanical resilience is high, withstanding shocks up to 2000 m/s² during indexing. Winding temperature is monitored by the AM-LPTC1000F sensor, allowing the drive to respond before thermal limits are reached. Multi-turn storage removes the need for homing after power loss, and the encoder’s self-monitoring works with self-cooling to maintain continuous availability.
