Networking capabilities for brushless DC motors

Offering greater motion control and automation integration, Crouzet Motors has announced the availability of CANopen technology for its brushless DC motors. The new communications protocol offering allows design engineers to connect multiple Crouzet brushless motors to the various components in their system, reducing wiring and installation costs while at the same time increasing system communications and integrity.

Crouzet's CANopen interface permits the connection of up to 127 brushless DC motors with a single, shielded two-wire cable. Data may be transmitted at speeds up to 125kBd at distances over 550 yards. At lower baud rates, the transmission distance can exceed three miles, making communications flexible to virtually any location. Under the communications protocol, motors can be controlled separately or together with high accuracy.

A unique feature of Crouzet's brushless DC motors with CANopen is that they can operate over a wide voltage range, withstanding up to 80VDC regenerative energy. In addition, these CANopen enabled motors utilise two safety inputs to cut down power in the motor even if the MPU has failed.

Embedded fieldbus control brings a number of other advantages that include integral protection for maximum life in severe environments, excellent reliability of data transmission, and immunity to external noise and vibration.

Crouzet's Brushless DC motors with CANopen interface are well suited for use in a variety of demanding applications ranging from medical, transportation, foodservice and precision agricultural equipment to packaging machinery, solar tracking, defence and industrial automation.

"By allowing our brushless motors to communicate with other components in the user's system, CANopen provides greater flexibility and data control than ever," says John Morehead, National Sales Manager, Crouzet Motors. "When you combine these advantages with Crouzet's already high performance brushless motor features like IP65 environmental protection and high torque density, users will find CANopen to be an excellent new tool for more readily automating their systems."
