Servo drives — also referred to as servo amplifiers — can be classified by the type of output stage they use: • Pulse-width-modulated (PWM) amplifier output stage or • Linear amplifier output stage. Of the two types, PWM drives are more common in general motion control applications because they provide more power to the motor, […]
Servo Drives
Application example: Motion components on a typical form-fill-seal machine
Form-fill-seal machines are used to package edible powders, dry food, and liquids into bags and pouches. It’s a common machine design that comes in versions for both continuous and intermittent operation. No matter the design, top design objectives for form-fill-seal machines are high throughput with minimal downtime and the ability to reconfigure the machine to […]
Digital printing pairs with a machine capable of handling its varied output
VITS International makes sheeting and finishing machines for packaging, printing, and converting. The OEM saw the digital-printing market needed finishing capable of commercial production speeds. So VITS designed and built the SPRINT Variable Data Finisher with a Bosch Rexroth drive and control platform to meet the demand. Digital inkjet printers can execute output comparable to […]
Difference between continuous ratings and holding continuous loads (an ac servo-motor terminology primer)
For applications primarily needing the holding of a load with little movement, there are special servo-motor sizing considerations. But confusion often arises from the terminology used to describe such designs — especially from the common use of the term stall in the servo-motor industry. Here we clarify the definition in context and then relate it […]
