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.
Utilising 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.
FOC technology allows higher torque, speed and power to be achieved, resulting in greater motor efficiency and reduced heat dissipation.
The 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.
Utilising 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 FOC.
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.
Safe operation at the motor's outer performance envelope is achieved using a built-in heat monitoring algorithm.
The Accelus 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.
