AM3000 | Synchronous Servomotors
Pole-wound motor series
For the AM3000 servomotors, the stator is not wound outside the housing but inside through a needle winder.
With pole winding, the copper wire is in close contact with the iron core. The wire insulation can be much thinner, since no pressing of the winding head is required. These measures lead to a significant increase in the proportion of “active” copper, which determines the torque value, so that the performance of the AM3000 series is approx. 25…35 % higher. An additional benefit is that the motors are significantly shorter than conventional models.
Sealed winding
The AM3000 servomotors are characterised by an extremely low moment of inertia, robust design and high overload capacity. The winding is sealed in order to eliminate air between the individual wires, since the thermal resistance of air is higher than that of epoxy resin. This further increases mechanical resilience, e.g. in case of vibrations.
The AM3000 Synchronous Servomotors are available with eight different flange codes. For each size, once the flange code has been defined, there is scope for variation in the length. The motors are offered with torques between 0.18 and 180 Nm and with a wide range of nominal speeds, so that for each application and gear ratio the motor with the optimum dimensions can be selected.
