AM88xx | Stainless steel servomotors
Based on the AM8000 technology, the AM8800 series has a stainless steel housing and is thus ideally suited for use in the food, pharmaceutical and chemical industries.
Highly dynamic
The AM8800 motors feature a low rotor moment of inertia and a very high overload capacity. Based on these technical data, the most dynamic applications can be realised.
High power density
The windings of the AM8800 motors are implemented using salient pole-wound technology. This gives rise to a high copper space factor. Due to the high slot space factor, high continuous torques can be attained. The end turns are very small, resulting in a small overall length. The fully potted stator provides for a thermally ideal binding of the winding to the motor housing. A further positive consequence of this is the mechanical protection of the winding wires against vibrations.
One cable technology
The one cable technology saves the use of an encoder cable. The encoder signals are transmitted digitally via the existing motor cable. The motors possess an electronic name plate for simple commissioning. The costs of laying the cable and the costs of the cable itself are lowered up to 50 % compared to conventional technology.
Design
The design is implemented without corners and edges according to the EHEDG guidelines for use in the food industry. The cable gland also has a hygienic design. The lubricants used are certified food-safe (FDA).
Robustness
Since the housing and motor shaft are manufactured from scratch-proof stainless steel AISI 316L, no corrosion creep or damage to the paint finish is possible. The motors are manufactured as standard with IP 67 protection; IP 69K can be ordered as an option, allowing the use of steam pressure cleaners. A sealing air connection to prevent the formation of condensation can also be ordered.
