2.1 Specifications of brushless servomotors SERIES 8
Servomotors SERIES 8 are brushless servomotors with rare earth permanent magnets
Nd_Fe - B (neodymium, iron, boron), sinusoidal technique, 6-poles, especially designed and
manufactured to be used in drives having high dynamic performances, high mechanical and
electrical precision, high overload capability and no necessity for maintenance.
Each "motor & sensors" (see paragraph 1.2.5) employed in the drives described in this
manual is made up of a servomotor SERIES 8 together with a brushIess/frameless
resolver (integrated in the servomotor), a temperature sensor and, when required, a brake.
SERIES 8 includes three axis heights and 22 different motors, with continuous stall torque
values ranging from 1.3 Nm to 37 Nm and nominal speeds equal to 1500 RPM, 3000 RPM
and 6000 RPM.
Table 2/1 contains some data concerning servomotors of this series; complete data regarding
dimensions, mechanical and electrical characteristics and performances of these
servomotors can be found in the catalogue 3AT K 93056 R004 ED 2/96, that can be
supplied on request; in the following pages of this manual we will refer to this publication as
the "Catalogue".
