Low-inertia servomotors suit high dynamic motion

AM3500 motors are particularly suitable for highly dynamic applications with high loads, for machine tool axes or gearless applications.
Beckhoff AM3000 low-inertia servomotors are predominantly used in highly dynamic motion applications.
The aim of most motor development efforts is to generate more torque with a design that is as compact as possible.
The challenge is that loads to be moved do not decrease accordingly.
On the contrary, with each machine generation, the trend is toward ever higher loads.
The aggravation of the inertia ratio between load and motor has a negative impact on control quality.
In extreme cases, the mechanical system can become unstable.
The inertia ratio can be optimised through suitable gearing.
However, this reduces the maximum possible speed, which means that in many applications, the required velocity can no longer be reached, so a larger motor and controller have to be used.
Beckhoff's AM3500 motor series avoids the associated higher costs.
The AM3500 motors are particularly suitable for highly dynamic applications with high loads, for machine tool axes or gearless applications.
In conjunction with higher rotor inertia, they offer the same benefits as the AM3xxx motor series such as the pole-wound stator winding, which significantly reduces the overall motor size.
The flanges, connectors and shafts of the new AM3500 series are compatible with the tried and tested AM3000 motors.
The new AM3500 models are available with flange sizes 3 to 6 and torques between 1.9 and 15Nm.
The rated speed range is 3000 to 6000rev/min.
Resolvers or absolute encoders (single or multi-turn) are available as a feedback system.
The standard protection class is IP64.
IP65/67 is available as an option.
This motor series is CE, UL and CSA-listed.
