4-quadrant positioning motion controller

Dunkermotoren USA's motion controller is designed to control brushless and brushed DC motors through CANopen networks or as a standalone with digital and analog I/O.

A 4-quadrant positioning motion controller with integral output stage is  available from Dunkermotoren USA. It is designed to control brushless and brushed DC motors as a slave in widely used CANopen networks or in stand-alone operation with digital or analog I/O.

Two versions of the new control are available in the same compact, power-dense package size of 51.7cc, slightly larger than a matchbox. The BGE 3508 model is designed for 10-30 Volt input with 75 W of continuous and 225 W peak power, while the BGE 6005model can produce 120 W continuous and 300 W of peak power with 60 Volt input.

These new controllers are suitable for use with brushless or conventional brushed dc motors similar to Dunkermotoren’s BG and GR/G ranges. Information about the motor’s rotor position can be supplied to the positioning controller either by the voltage or by an encoder in the case of commutator motors or, for brushless motors, by Hall sensors or an incremental encoder. The controls incorporate protection against over-voltage, low voltage and excessive temperature.

If 4-quadrant digital speed control is desired, the control can be commanded to run in either direction, stop and hold with torque, and stop without torque (coast) through digital inputs. Other inputs can switch between programmed speeds or allow for a v ariable analog speed reference. Accel/decal ramps for the motor can also be programmed. The control reportedly offers the capability for a motor to function as a stand-alone, programmed servo which interfaces to the rest of the machine via digital and analog I/O.

The new BGE 3508/6005 controllers reportedly offer many different modes of operation to choose from, such as analog or digital torque control, analog or digital speed control and digitally selectable position control (relative, absolute, and modulo).

"The CAN bus functionality of this drive makes it a powerful tool in industrial applications, allowing decentralized control and a reduction in complexity of the overall system," said Jonathan Doyle, applications engineer, Dunkermotoren USA.

Designed for volume OEM applications, the Dunkermotoren BGE 3508/6005 controllers offer a design alternative for restricted space applications where the additional length of an integral control motor may not be feasible. They can also be encapsulated to provide additional protection in extreme environmental conditions.

CANopen is the most widespread application layer in non-automotive control applications and market researchers predict that by 2015 some 400 million CAN chips will be used annually in a wide range of applications such as medical equipment, heavy vehicles, door control systems and throughout commercial and industrial automation systems.

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.
