Motors: Dunkermotor

January 30, 2012

DunkermotorMachinery motion control manufacturer, Dunkermotor, has released its 2012 catalog of low voltage Brushless DC and Intelligent Servo Motors. The expanded catalog includes detailed specifications on custom configurable BLDC motors, controls, gearheads, brakes, encoders and accessories and is now available for complimentary download at the Dunkermotor website or by email request for hard copies.

The Dunkermotor product line is based on five frame sizes of high power density low voltage BLDC motors, ranging from 32 to 75 mm (1.26 to 2.95 inches) with continuous output power ratings up to 530 W (0.7 hp). They are available as motors only or can be configured in infinite varieties with separate or integral controls, incremental or absolute encoders, matched parallel shaft and right angle gearing, as well as power-off or power-on brakes. 

New features in the 114-page catalog include:

  • Profibus and EtherCAT interface options added to integral control 45, 65 and 75 mm BLDC motors to allow slave operation in motion control networks
  • 20 new pages of information and specifications on 5 sizes of planetary gearheads, including special low noise versions, with continuous torque ratings to 160 Nm (1416 in-lbs), as well as 4 sizes of right angle worm gear reducers
  • Addition of integral commutation electronics option to 32 and 42 mm BLDC motors to permit simple two-wire operation in many industrial and commercial pump applications
  • New BGE 30100 standalone control added for use with battery powered brushless motors up to 500 W
  • Compact new CANopen-Profibus gateway to allow CANopen motors slave operation in a Profibus network

"This new catalog had to have one-third more pages in order to fully cover the variety of custom configurations which are possible with our fully integrated product line, " said John Morehead, Dunkermotor vice president, business development. "OEMs are increasingly looking for sole source responsibility solutions and Dunkermotor strives to achieve that in the fractional horsepower motion control market."

"It's surprising how many OEMs today have to work with their motor suppliers like an audiophile did 25 years ago," said Morehead. "They're still trying to put together motors, encoders, controls, amplifiers, gears and brakes, often from different sources, just like when you had to try to coordinate tuners, preamps, amplifiers, tape decks, speakers and who knows what else, along with the requisite rats nest of wires and cables. Today, thanks to digital technology and products like the iPod, the component audio market exists only for those with the most fanatical tastes and a lot of disposable income.  Similarly, an all-in-one integrated intelligence servo motor can rotate a shaft exactly the way the OEM wants, much more easily, in a smaller space and with a significantly better value proposition than the old way of specifying and achieving motion control."
