The magnetic circuit of DYNASERV employs the
magnetic bias method, in which a rare-earth permanent
magnet with a high magnetic force is housed in the
stator core. As in the fig ure below, this mechanism
generates a high rotating torque, which is proportional
to the square value of the sum of the two magnetic
fl uxes. As a result, the direct drive (DD) motor offers an
unprecedented torque-weight ratio.

Intelligent Drivers are drastically improved the basic Stator Core
performance of DYNASERV. The employment of
digital positioning and speed control technologies and Coil
four-fold resolution are among the factors reducing the
Permanent magnet
position setting time conventional DYNASERV to less
than half that of DYNASERV.
Rotor
The standard-equipped feed forward function also
contributes to the reduction of the position setting time. DM1A-150
DYNASERV uses a special high-rigidity bearing to
support rotations, so it produces a very small amount
of dust. The cleanliness of DYNASERV
is proven by a Class-10 rating, which
means the maximum number of pieces
of dust whose particle diameter
exceeds 0.5 μm is 10 per square foot.
The gear-less structure ensures
the long product life.

Features and Principles
High Torque Highly Accurate
DYNASERV is powered by a newly developed encoder,
to which the high resolution and accuracy of DM
Series drivers can be attributed. The resolution of
DM1A Series is 4,096,000 pulses per revolution. DM1B
series is 2,621,440 pulses per revolution. The absolute
