Description 0 52 Motors of the BG440 series are EC motors (brushless DC-motors) with integrated rotation speed electronics. BG440 series comprises two designs with different dimensions and output power of 20 W and 40 W. The EC motor featuring a fully assembled planetary gearing is a compact drive in electric spindle positioning operations of the multiconDrive system. It provides a separate round connector output enabling direct motor connection to the spindle position display (N 142, N 152). This "interface" provides the motor with the control signals for "clockwise", "counterclockwise" and "off" as well as with the signal for recalling two permanent motor speed parameters relating to high and low speed. Already predefined ramps for acceleration respectively deceleration secure smooth motor start and slow-down. 01 Firmware 01 Firmware version 01 Gear transmission 52 ø52 mm Scaling 0 50:1 Performance 25 20 W 50 40 W Accessories Motor supply cable 1.5 m, 8-pin mating conntector Z 165.M02 Motor supply cable 3 m, 8-pin mating connector Z 165.M03 Motor supply cable 10 m, 8-pin mating connector 2 www.baumer.com/motion 19/5/2015 Z 165.M01 Subject to modification in technic and design.
