New CANopen networking for brushless dc motors boost safety

Crouzet’s CANopen interface permits connection of up to 127 brushless dc motors with a single, shielded two-wire cable. Data may be transmitted at speeds up to 125 kBd 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.

Crouzet’s brushless dc motors with CANopen can operate over a wide voltage range, withstanding up to 80 volts DC regenerative energy. Plus the motors use two safety inputs to cut down power in the motor even if the microprocessor 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, defense 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,” said John Morehead, Crouzet Motors National Sales Manager. “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.”For more information, contact Crouzet Motors.
