Cooling

Fittings

Two coolant ports are fitted to the rear of the MC0-500 enclosure. These ports are used for motor controller cooling under normal operation.

The coolant ports and cooling geometry are symmetric and coolant flow is allowable in either direction.

However, due to internal heating characteristics it is recommended that when viewed from the rear the right port is used as the inlet, and left port as the outlet.

It is recommended to use a semi-rigid tube with:

\[\text{OD = 8 mm, ID = 6 mm}\]

As-provided, MC0-500 ships with two straight barbed tube fittings. However these can be replaced with any 1/4”-18 NPT threaded fitting.

The tubing should be rated for at least the maximum coolant pressure.

Coolant

The coolant plate is rated for a maximum inlet pressure of 310kPa (45 psi) relative to ambient. Pressures in excess of the maximum may cause leakage of coolant and degraded performance.

Internal testing was performed with a coolant consisting of a 50/50 mix of water and glycol. The maximum recommended inlet temperature is 60C at full load operation.

Flow Requirements

The recommended flow rate to MC0-500 is 20 LPM.
