EC motor EC303, size 3, installation length 219 mm - Bosch Rexroth 0608701017

For joints in the medium torque range, system builders use size 3 spindles of the Tightening System 350. The EC303 EC motor is their drive. With 219 mm installation length and 1.3 kg net weight it is one size up from the EC302, yet compact enough for multi-spindle heads.

Benefits

• 219 mm installation length, only 22 mm longer than the size 2 motor
• Brushless, electronically commutated drive, no brush changes in the maintenance plan
• Matches size 3 gearboxes such as 3GE27 or 3GE67
• Same system logic as every Tightening System 350 module, so replacement and retrofit need no new control architecture
