Updated 2020 ⚙️ Gearboxes provide torque multiplication, speed reduction, and inertia matching for motor-driven systems. Servo systems, specifically, require gearboxes that can supply not only high torque with low added inertia, but also high precision and stiffness. One type of gearbox meets all these criteria while providing relatively long operating life with low maintenance requirements […]
Servo Motors
What is a hygienic servo motor?
Servo motors find use in a wide range of applications, from cleanroom settings to dirty environments where they face exposure to varying temperatures, pressures, and even liquid and caustic chemicals, in addition to dust and debris. One specific class of servo motors called hygienic (or simply stainless steel) are motors specifically designed to satisfy hygienic […]
Frameless motor basics video: Operation, integration, and application
Frameless motors are rotor-and-stator subcomponent sets that aren’t prefixed in a traditional motor housing. They don’t include an output shaft (or shaft-support bearings) either. Instead, the OEM or design engineer works with the supplier to tightly integrate the frameless motor stator and rotor directly into the machine and framing. Watch this video for more: However, […]
How does cabling contribute to servomotor electrical noise problems?
The sources of electrical noise can be varied, but one of the most common sources is from the high-frequency signals generated by variable frequency drives (VFDs.) This noise, called electromagnetic interference (EMI), can be picked up through cabling. Cables themselves can be manufactured with special shielding to guard against EMI issues. The purpose of cable […]

Hybrid servos vs. standard servos: How do they stack up?
A new type of integrated hybrid servo motor is finding use in direct-drive applications where it offers lower cost, smaller size, and higher efficiency than conventional servo motors. Donald Labriola P.E. QuickSilver Controls, Inc. No single motor type has advantages in every application. Direct-drive applications favor so-called hybrid servos while high-speed geared-down applications tend to […]
How notch filters and low-pass filters reduce resonance in servo systems
Servo systems experience resonance due to compliance or backlash in mechanical components such as gearboxes, screw drives, and couplings. Resonance reduces system performance, can cause audible noise, and in extreme cases can even damage hardware. Servo tuning is the process of setting controller gains to optimize servo performance, but as gains are increased, resonances typically […]
