Swedish Innovative Servo Motion Engineering Since 1994 Electric data Mechanical data (resolver feedback) Holding brake For higher torques, see next page. Overheat protection consists of triple PTC thermistors. Protection class Insulation class HDD motors comply with The insulation system complies the requirements for IP with the requirements of EEC LV 65. IP-67 is available on Directive 73/23/EEC and request. 93/68/EEC. Test report Motor name structure Flange size Stator length Winding HDD = shaft motor, ICM = internal coupling motor.

Current at 9Q2C temp rise, in Ampere rms. Winding The HDD/ICM motors are capable of high peak torques. The coupling inside the ICM is however limited to 15 Nm peak. At very high peak torques the permitted pulse time is very limited as a high current in a very small motor causes rapid temperature rise in the copper winding. The protection thermistor will not react fast enough to protect the winding during high pulse loads. A 20A rms current to a HDD09N-Pa will give some 23.3 Nm, but the copper winding temperature will increase with some 42°C per second. This is not a problem for short pulses of...
