Danaher Intros 5 Frameless Servo Motor Sizes
Frameless servo motors.
Wood Dale, IL — Danaher Motion ha has added three frame smaller sizes to its family of innovative Cartridge DDR
direct drive rotary servomotors. Now available in five frame sizes ranging from 4.25-in. square to 13.78-in. square with four stack lengths per frame, the motors are described as a completely unique category of direct drive technology that uses pre-engineered components, an integrated, factory-aligned high resolution feedback device and an unusual bearing-less design that facilitates maintenance-free "mount and run" operation in under 30 minutes.
According to the company, conventional servo systems typically include up to 15 mechanical transmission components per axis of motion that can limit performance and reliability while increasing operational costs. Frameless direct drive systems can take weeks and even months of design and integration time. These new motors bridge the gap by eliminating all mechanical transmission parts to provide maintenance-free operation in just minutes.
Users will also benefit from increased machine uptime, a noticeable 20dB noise reduction, and up to a 50 percent increase in accuracy and torque density compared with traditional servo systems. The motors will reportedly reduce operating costs by more than $10,000 on a single axis of motion when compared to conventional servo systems.
CE marked and UL listed for global application, the motors are available with 240V, 400V, and 480V voltage ratings for maximum design flexibility and robust operation. They provide 4.57 to 510 N-m continuous torque, peak torque to 1017 N-m, and speeds to 2500 rpm.
