Servo drive range has exceptional power density

Elmo Motion Control continues to develop innovative high-power and high-intelligence density servo drives for extreme environments with its new Gold Bee series. Available with full support from Heason Technology, the ultra-small PCB mount package, measuring just 35mm x 30mm x 14.4mm, can deliver up to 4000W of power with current ratings to 50A at 100VDC. The powerful drive is packed with many advanced features including a choice of EtherCAT or CANopen networking, Safe Torque Off, and multiple feedback options. As part of company’s servo drive range the diminutive Gold Bee is built for extreme environment conditions with wide current control and a current loop dynamic range of 2000:1 for high bandwidth servo performance. It can be used with brushed and brushless servo motors and is configured for a predetermined DC Voltage and current range. Nominal supply voltage through the range is 85VDC or 170VDC with continuous current to 30A and peak current at 2x continuous ratings for standard versions. The company also offers ‘no peak current’ versions where continuous current is up to 50A. Such current control is made possible with their thermal management drive design that realises safe and reliable high-power density and cutting-edge performance. The drive is specifically built for extreme environments with temperature ratings of -40C to +70C and vibration up to 14Grms. The drive features dual feedback inputs with provision for absolute serial encoders, incremental encoders, digital and analogue halls as well as resolvers - making the choice of feedback very flexible to suit a wide range of servo motor technologies. Servo loop sampling times are as fast as 50 microseconds for current, velocity and position.
