B&R’s liquid-cooled three-phase synchronous motors feature high power density with compact outer dimensions. Integrated water cooling enables more compact sizes and prevents the machine or the switching cabinet from overheating. Doing away with energy consuming and noisy fans saves space, reduces emissions and lowers costs. The life-span increases significantly because the motor parts except for bearings are free of wear. Intelligent connection technology for power and encoder connections using circular connectors or terminal boxes simplifies installation considerably. The 8KS series motors are available in four sizes with a rated speed of 1,100 1/min to 2,200 1/min and a maximum speed of 4,500 to 10,000 1/min. The rated torque is between 8.3 Nm and 605 Nm. The motors can be controlled with ACOPOS or ACOPOSmulti servo drives.
