Frequently Asked Questions
What is the permissible ambient temperature range specified?
The permissible ambient temperature is from 0°C to 40°C for continuous duty operation. The range ensures optimal insulation and prevents excessive thermal stress during extended use.
How does storage temperature affect motor longevity?
The storage temperature range of –20°C to +80°C maintains material stability and insulation quality. The control of storage conditions minimizes condensation and corrosion during inactive periods.
What is the significance of altitude limitation specification?
The maximum installation altitude of 1000 meters above sea level ensures proper cooling and air density consistency. The altitude restriction supports accurate thermal behavior and expected torque output.
How does protection class influence environmental durability?
The IP65 protection rating prevents dust ingress and resists low-pressure water jets from any direction. The sealing integrity enables reliable integration in environments with moderate dust or moisture exposure.
What environmental considerations affect varnish and coating choice?
The prime coat black varnish RAL 9005 resists oxidation and mechanical wear under normal industrial conditions. The coating preserves housing durability and enhances corrosion protection during long-term operation.
