Conventional brushless DC motors are constructed with a permanent magnet rotor located inside a wound stator. But one type of DC motor is designed with the rotor on the outside and the stator and housed inside the rotor. Permanent magnets are mounted on the inner diameter of the rotor housing (sometimes referred to as the […]

Brushless dc motors for industrial power tools: Comparison of options including slotless motor variations
Industrial power tools have operating profiles that differ from those of most other motor-driven applications. That’s why motors that go into these tools need specialized designs. By Thomas Baile, Business Development Manager | Portescap Most electric-motor-driven designs demand torque for the entirety of their motion. In contrast, power tools for fastening, gripping, and cutting applications […]
How does a fixed-ratio traction drive work — and potentially outperform gear reducers?
Traction drives have been used for power transmission for more than a century. Now today’s advanced manufacturing and materials have made an innovative new traction drive possible. How traction in general works — and how the new traction drive works Much like the wheels of train cars, traction drives use normal force to generate usable […]
GAM right-angle gearboxes: EPR and PER Series come in NEMA and metric variations
EPR Series right-angle bevel planetary gearboxes from GAM Enterprises deliver the quality and cost advantages of the manufacturer’s EPL inline gearboxes but in a right-angle configuration. The gearboxes come with precision-ground spiral bevel gears on the input stage and GAM Enterprises EPL or PE inline gearbox elements on the planetary stage. EPR Series planetary gearboxes are […]
Simplified CANopen setup for POSITAL IXARC magnetic encoders
POSITAL’s IXARC new magnetic absolute encoders with CANopen interfaces are now available with an optional “connection cap” that makes device configuration and troubleshooting simpler and more intuitive. For previous generation IXARC magnetic encoders with CANopen interfaces, device setup was accomplished by updating software parameters, requiring special tools and expertise. The connection cap contains three rotary […]
How do pulse-duty servo drives and motors differ from continuous-duty versions?
Servo systems are applied in a wide range of applications, from intermittent operations that require high torque output for quick acceleration and deceleration — such as pick-and-place from a conveyor — to processes that call for nearly uninterrupted operation with constant speed and torque requirements — such as printing, roll feeding, and labeling. Given these dissimilar application requirements and […]

How can a universal motor operate on either DC or AC supply?
A universal motor is a series-wound motor — meaning that the field and armature windings are connected in series — and is mechanically commutated with brushes and a commutator. Although its construction is very similar to a series-wound DC motor, a universal motor incorporates several modifications that allow it operate properly on either DC or AC […]
