Description

Servodrive AC torque motors serie STR are high pole sychnronous servomotors. Its characteristical parameters makes this serie ideal for high accurate direct drives, for machine-tools and measuring machines. Stator ring is build-up out of high energy permanent magnets. The stator packet is made of cold rolled steel sheets and pressed together. There is an AC star connected winding in stator slots. The stator packet is pressed in to a alumunium cylinder. This cylinder have a machined water way for motor cooling.

Standard Servodrive torque motor is optimized for water cooling. There is machined a water way (cooling chanels) on the motor surface. Complete STR serie is based on water cooling design. All parameters shown here are for water cooled motors. For an applications, where water cooling is not possible, the motors can be optimized for air cooling. Air cooled motor has a smooth surface. Motor has to be attached (mounted) into some assemble so that the heat can be conducted out of motor. This machine surface has to be at least 3x higher that motor surface to maintain proper cooling conditions. Rated and continuous torque of air cooled motor is approximately 40 to 45% of water cooling rated and continuous torque. Peak torque of air cooled motor stays the same.
