Brushless servo drives are DSP based all-digital, precision servo drive amplifiers, which are able of supplying “16 A peak” current constant, as well as “32 A peak” up to 230 VAC. The brushless servo drives are designed to perfectly control the position or velocity and torque of a number of brushless torque and servo motors. The design of this servo drive simplifies the commissioning and set up of the brushless servo motors, as the system software of brushless servo drives needs little more than the ordinary ones.
Features of brushless servo drives:
- Several models which cover the major parts of the requirements of the servo application
- Line operated, 50/60 Hz, 115-240 VAC, single or three phase
- The complete digital design of brushless servo drives simplifies the drive tuning and drive set up and removes the analog drift
- Complete fault protection and “optically isolated I/O”
- PWM, ±10VDC, encoder-follower and step-direction control inputs accommodated
- Internal regenerative power control circuit, which requires an external resistor
- Graphical client interface based on PC for motion control, monitoring and commissioning. This interface is attached with the drive through an “optically isolated USB port”.
Benefits of brushless servo drives:
- High efficiency or power saving- The original drive technology of brushless servo drives use low power and offer a high efficiency. It represents a great money saving technique on the 24/7 application than the ordinary servo drives
- High inertial loads- The brushless servo drives use “sophisticated motion control algorithms” to take the advantage of high-torque capacity, offering direct-drive of high inertia loads such as the belt drives and flywheels. It is much more than the traditional servos. This servo drive also provides a smooth responsive pointing control.
- More torque in a lesser price- Brushless servo drives provides 2-4 times more constant torque in lesser price ($300-400 less) than the conventional servo motors.
