AM3500 | Synchronous Servomotors

New motor technologies enable more and more dynamic motors with lower inertia. The aim of most motor development efforts is to generate more torque with a design that should be as compact as possible. The challenge is that loads to be moved do not reduce proportionally – on the contrary, with each machine generation the trend is towards higher loads.

 

For improving the inertia ratio, it may be advisable to introduce gearing or to increase the gear ratio for existing gearing, since the reduction in load moment of inertia is proportional to the square of the gear ratio. However, the resulting lower speed/velocity is often unsuitable, leaving selection of a larger motor as the only solution. Beckhoff offers the AM3500 motor series in order to avoid the associated higher costs for the motor and servo controller. These motors are particularly suitable for highly dynamic applications with high loads. In conjunction with higher rotor inertia, they offer the benefits of the AM3000 motor series in the form of the pole-wound stator winding, which significantly reduces the overall size.

Resolvers or absolute encoders (single or multi-turn) are available as feedback system. The standard protection class is IP 64; IP 65 is available as an option.
