For a machine standing outdoors, writing just “outdoor use” on the order is not enough; the mounting position, exposure to sun and rain, the day-night temperature swing, proximity to the sea, whether the machine will sit idle for long periods and the direction of the cable entry should each be stated. These notes show whether a standard motor is adequate and whether extra protection is needed.

DRG-180M-4 18.5 kW 1500 rpm cast iron frame DRG three-phase motor – ordering a motor for outdoor use

Notes to add to the order

  1. Mounting position: Horizontal, or vertical with the shaft down? For vertical shaft-down mounting, ask whether a canopy is needed to stop water entering through the fan cover.
  2. Overhead protection: Whether there is a shelter or sheet-metal cover above the motor.
  3. Sun: Direct summer sun raises frame temperature; include it in the ambient temperature description.
  4. Condensation: Cold nights followed by humid mornings can lead to water collecting inside the motor.
  5. Salty or polluted air: Corrosion speeds up on the coast or near a fertiliser plant.
  6. Idle periods: On a seasonal machine the motor may stand still for months.
  7. Cable entry: The cable gland should not face upwards; an entry facing down or to the side is preferable.

How much does standard protection cover?

DRG motors are rated IP55; they are protected against rainwater and spray, but not against submersion or standing in puddles for long periods. Requests for special paint or extra surface treatment count as buyer-specific preparation; such products are excluded from returns, so clarify the need before ordering.

A note on warranty

Failures caused by moisture, corrosive environments or inadequate ventilation are not covered by the warranty. A simple shelter and the right cable entry reduce these risks considerably.

For field and garden applications, see the agricultural machinery motors page; if you need a robust frame, look at the cast iron options in the shop.
