Protection Class
Protection class IP69K has been created for high pressure and high temperature cleaning
according to DIN 40050-9. Code “6” (Dust tight. No ingress of dust.) defines the protection
against solids. Code “9K” (Protected against close-range high pressure, high temperature spray
downs.) defines the protection against liquids.
IP69K protection class is for static use only. This rating does not account for water present
while the shaft is rotating. For applications that require sealing during rotation, please contact
Kollmorgen Customer Support.
Insulation Material
AKMH motors are insulation class F according to IEC 60085 (UL1446 class F).
Surface
The AKMH motor housing is made from 316L or 1.4404 stainless steel with surface roughness < 0.8 μm pursuant to
EHEDG requirements.
Protective Device
AKMH motors are fitted with an electrically isolated temperature sensor (rated temperature 155°C ± 5%) and
integrate into the motor temperature monitoring system (e.g. Kollmorgen’s AKD). The standard motor option is
equipped with a KTY83-110 equivalent thermal sensor and serially connected PTC thermistor, with a threshold limit
setting of 2500 Ohms.
