Natural convection
Rexroth motors in standard design are self-cooling. The heat dissipation is
realized via natural radiation to the ambient air and by heat conduction to the
machine structure. The nominal data are achieved at ambient temperatures
of up to 40 °C. Sufficient heat radiation must be ensured by the installation
situation. Unhindered vertical convection has to be ensured by a sufficient
distance of 100 mm to adjacent components on the side surfaces.
Contamination of the motors reduces heat dissipation. Pay atten‐
tion to cleanliness!
