Kollmorgen AKMH™ Stainless Steel Washdown Motor Technical Guide

AKMH™ Technical Guide

General Technical Data

Ambient Temperature: 0...+25° C for site altitude up to 1000 m amsl (at rated values).

It is vital to consult our applications department for ambient temperatures

above 40° C and/or any enclosed environment.

Power De-rating:

(currents and torques)

1% / °C in range 40° C...50° C up to 1000 m amsl for site altitude above 1000 m amsl and 40° C

» 6% up to 2000 m amsl

» 17% up to 3000 m amsl

» 30% up to 4000 m amsl

» 55% up to 5000 m amsl

For site altitudes above 1000 m amsl, no de-rating with temperature reduction of 10° C / 1000 m

Temperature De-rating: If the application requires de-rating due to lower motor surface temperature,

please contact our applications department.

Ball-bearing Life: ≥ 20.000 operating hours

Phasing Diagram - All Motors

• When the motor is rotated C.W. (viewed from drive shaft end), the

following Bemf voltage waveforms result:

• Voltage phase-U, leads Voltage phase-V, by 120-degrees

• Voltage phase-V, leads Voltage phase-W, by 120-degrees

• Voltage phase-W, leads Voltage phase-U, by 120-degrees

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.
