  • Pitch Control Drive

    Pitch Control Drive is designed to be installed in sets of three, within a wind turbine hub in order to control the pitch of the blades. The drive operates in either position, velocity or torque mode. The drive can receive Analog commands or CANopen® commands from the Pitch Control system. The product interfaces two feedback devices (dual-feedback) to enhance control accuracy due to motor’s gearing. During its normal operation the drive monitors and charges the external (to the drive) capacitor’s bank which is used during shut-down scenarios to perform a controlled move of the blade to its neutral position. The proposed Pitch Control Drive is very cost effective.

  • MDU - 12 Axis Multi Drive Unit

    Designed for a custom application in the Carpet Tufting industry, this Multi-Drive Unit (MDU) consists of 12 independent servo drives assembled on a 9U PCB. Depending on the end-user’s requirements, anywhere from 100 to 200 of these MDUs may be in use in a single machine. A central CPU provides a dual CAN bus interface for the MDU, and this CPU communicates information over an SSI bus between the CAN bus and the servo drives. A CAN Communications Processor controls the process and communicates with the MDUs.

    The servo drives operate in Gear Mode, following a Master Encoder value that comes from an encoder mounted on main shaft of the machine. This value is broadcast every 1 milli-second over one of the CAN channels to all motors. The other CAN channel is used to transmit gear values independently to each servo drive, and to get status information back from the MDUs. A debug channel on the 1msec bus enables the CAN Communications Processor to retrieve periodic data from the servo drives, to be used for data recording and trend analysis.

    The motivating factor behind the development effort was the need to have easy, faster setup and programming flexibility in controlling up to 2200 axes per machine, replacing a mechanical CAM shaft.

  • Modular Servo Control System

    The Modular Servo Control System is a high power control chassis used to drive up to 8 linear variable reluctance motors. The chassis includes cooling fans, and a control signals distribution board for easy connection to the machine controller. Space is provided for the system power supply and the chassis is shipped with power distribution wiring in place.

    The system is modular since it is designed to serve machines that have 3, 4, 6 or 8 axes. The servo drives are independent of each other. They perform current control of the motor’s three independent phases, and receive a commutated analog current command from the machine controller.
