The length of the BG45 x 15SI has been ?reduced from 120mm to 88mm and the length of the more powerful BG45x30SI was reduced from 135mm to 103mm.
Under the banner of ”everything on board” these high power density, under 100 watt, compact intelligent servo motors offer true 4 – quadrant digital speed control.
The new BG45SI ?motors, with a height and width dimension of 44mm feature newly designed digital control and power electronics that offer a significant overall package size reduction of over 25% compared to its predecessors.
In addition, the motor connector design has been updated for further space saving and convenience in mounting and connection.
With a 12 or 24 volt power source, at a nominal speed of 3000 rpm, the longer of the two units, the BC45x30SI ?is continuous duty rated for 80 watts power output. Based on the improved design, however, the motors can achieve peak powers of four times the continuous duty rating and, therefore, a starting torque of up to 100 Ncm is possible. The motor target speed can be set using an analog +/-10VDC input signal. Alternatively, different set speeds can be selected via digital inputs using a simple start-up software.
The drive has a total of 4 digital inputs. Of these, two are for selecting the four operating conditions: rotation clockwise/counter-clockwise, stop with free running, and stop with holding torque. The other two digital inputsare designed for the selection of the fixed motor speed with acceleration and deceleration ramps.
In addition, there are 3 digital outputs with pulse output functions (12 pulses per revolution), the direction of rotation – assigned and fault output signal.
Other than long-life ball bearings, the motors contain no other wear-prone mechanical components and are, therefore, ideally suited for continuous duty applications.
The BG45SI motors are part of a complete family of modular components such as planetary and worm gearboxes, encoders, and brakes which offer virtually infinitely variable configurations to meet most application requirements.
These versatile intelligent brushless motors are designed for dependable, long-life use in a wide variety of factory and commercial automation, as well as medical and laboratory equipment applications.
