AM87xx Servomotors with anodised housing

AM87xx | Servomotors with anodised housing

The anodised servomotors from the AM8700 series combine the advantages of the highly dynamic AM8000 standard servomotors with the requirements of the packaging and food industries.

Like the AM8800 motors, the AM8700 motors meet hygienic design requirements and are therefore intended for use in the food, pharmaceutical and chemical industries. Due to the specially treated aluminium housing of the AM8700 motors, the housing surface can also withstand harsh operating conditions, but nevertheless offers ideal thermal conductivity, so that there is no derating of the motor power. In comparison with the stainless steel housing the aluminium housing is very light and therefore offers a further benefit, e.g. when moving axes.

The windings of the AM8700 series are implemented using salient pole-wound technology. The benefit is a high copper fill factor. High torques can be attained due to the high slot fill factor. The fully potted stator provides for a thermally ideal transition from the windings to the motor housing. Another advantage of full potting is mechanical protection of the winding wires against vibrations.

The AM8700 motors have IP 69K protection (not including the output shaft) as standard and can be equipped with a sealing air connection to prevent condensate formation. The OCT direct cable outlet is also implemented in hygienic design. All lubricants used are FDA-certified as food-safe.

For a wide performance range the anodised motors are offered in the flange sizes F3 to F6, each in three different overall lengths.
