Field oriented control technology allows higher torque, speed and power to be achieved, resulting in greater motor efficiency and reduced heat dissipation
The new Accelus all-digital servoamplifier from Copley Motion
Systems is a major advance in motor drive technology.
field oriented control (FOC) technology to maintain a precise
90deg displacement between the magnetic fields of the rotor and
stator at all motor speeds, the Accelus raises equipment
throughput, simplifies cooling, and cuts costs.
allows higher torque, speed and power to be achieved, resulting
in greater motor efficiency and reduced heat dissipation.
increase in power means that a smaller motor can be used in
certain applications, while reduced amplifier and motor heat
dissipation, and the associated increase in motor performance,
enables convection cooling to simplify many motion system
designs, hence cutting system costs.
The Accelus is used in
conjunction with Copley's CD-based CME2T software.
screen prompts and directions, this incorporates a powerful auto
phasing algorithm to complete system commissioning with a single
mouse click, and auto tuning algorithms to automatically tune the
servoamplifier's current loop to establish wide bandwidth
The high peak current of 300% of continuous current provides
rapid motor acceleration to minimise robotics positioning time
and increase throughout.
Sinusoidal motor commutation ensures
ripple-free drive torque to minimise equipment vibration and
ensure uniform pressure in machining and drawing operations.
operation at the motor's outer performance envelope is
achieved using a built-in heat monitoring algorithm.
servoamplifier is compatible with many popular controllers to
provide system versatility and permit a direct upgrade path from
stepper motors to high-torque servomotors.
It is built on a low
cost, single layer PCB that can be mounted flat or edgewise.
Available in two models to cover different operating voltages, a
range of mounting and packaging options are available to support
the design of multi-axis drive systems.
