"The Watt Drive is really a hybrid AC vector motor that can provide closed loop control for acceleration, deceleration and positioning motion profiles with the use of our P6000 controller, as well as other high-end programmable inverters," explains Chris Popp, Diequa's director of marketing and technical support.
"This combination can satisfy many packaging machinery speed and motion requirements that don't require the full capabilities of a servomotor, yet at a lower cost than servos."
Twelve sizes of the Watt Drive motor are available in torque capacities ranging from 1.8 to 66 Newton meters, and operating speeds up to 6,000 rpm.Designed for both 50 and 60 Hz frequency systems, the motor includes an integrated encoder with a resolution of 1,024 steps per revolution and a 10 to 30V HTL signal, which can also be transmitted to a PLC.
"The motor provides higher torque and smoother speed variations than stepper motors, and more accurate speed and motion control than standard AC or DC motors, adding flexibility to the machine drive design process," Popp
Options for the Watt Drive motor include brakes for load holding safety during dwell time, and forced cooling kits to eliminate heat build up during continuous slow-speed operation.Popp
adds that combining the motor with the available range of Diequa's Watt Drive helical reducers provides a cost-effective gearmotor package in both inline and right angle configurations.
"This makes the Watt Drive suitable for use in a wide range of packaging automation needs such as intermittent part feeding, cyclic conveyor movements, indexing profiles and accurate variable speed process control," he
