Intelligent servo motor size reduced 25%, retains full power

Dunkermotor reduces size of its 45mm iBLDC (Intelligent Brushless) motors with integral 4-quadrant speed controls by 25%, while maintaining power, torque, efficiency.

Responding to customer requirements for smaller size, higher power density intelligent servo motors, 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.)

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 with programmable features.

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 watts (1/10 hp) 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 N-cm (142 oz-in) 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 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 and are, therefore, ideally suited for continuous duty applications.

"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," said John Morehead, vice president, business development for Dunkermotor. "Next to reducing parts count, being able to reduce size is one of our top customer interests and that has driven this improved new design."

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.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
