Dunkermotor Reduces Servo Motor Size by 25%, While Retaining Full Power

By Miles Budimir | April 17, 2012

Elgin, Ill. –Dunkermotor has been able to shorten its iBLDC™ (Intelligent Brushless DC) motors with integral 4-quadrant speed controls in the 45mm frame size by 25%, while maintaining the same power and torque capabilities and motor efficiencies. The length of the new BG45x15SI was reduced from 120mm to 88mm (4.7 to 3.5 in.) and the length of the more powerful BG45x30SI was reduced from 135mm to 103mm (5.3 to 4.0 in.). 

The new BG45SI motors, with a height and width dimension of 44 mm (1.73 in.) 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 BG45x30SI is continuous duty rated for 80 W (1/10 hp) power output. Based on the improved design, the motors can achieve peak powers of four times the continuous duty rating with a possible starting torque of up to 100 N-cm (142 oz-in).

The motor target speed can be set using an analog +/-10VDC input signal. Alternatively, different set speeds can be selected via digital inputs using 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 inputs are 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, making them suited for continuous duty applications.
