POSITAL FRABA encoders for closed-loop motor feedback allow upgrades to existing motion control applications. The mechanical drop-in replacement encoders have the same footprints as US Digital’s E5 models and Broadcom’s (Avago) HEDS-5500 models. POSITAL kit encoders provide absolute position feedback — to give controls complete information on the physical position of the mechanical components they’re […]

Seattle-area Motion Industries distribution center now open
Motion Industries, a leading distributor of maintenance, repair, and operation replacement parts and a wholly owned subsidiary of Genuine Parts Company, has opened the doors for business at its new distribution center (DC) at 4401 D Street NW, Suite A, in Auburn, Wash. The facility is managed by Ryan Mort. The DC’s strategically chosen location […]
Three ways to reduce heat when operating a step motor
Reduce motor heat by reducing idle and running current — or switch to closed-loop control. Eric Rice | Applied Motion Products Step motors are widely used motion-control devices because of their simple setup and accurate positioning with an open-loop configuration. But problems associated with heat generation can arise. That’s because the drive that powers an […]
Three-axis gimbal mount from OES: High resolution and stability
A new Optimal Engineering Systems, Inc. (OES) AU300-AER three-axis gimbal mount features full 360° rotation of each axis. This three-axis gimbal mount handles loads to 10 kg (22.5 lb) and has a clearance of 300 mm x 300 mm, (11.8 in. x 11.8 in.) around the roll axis stage. The azimuth stage rotary table mounts […]
What is a Halbach array and how is it used in electric motors?
A Halbach array is arrangement of permanent magnets that creates a stronger field on one side while reducing the field on the other side to near zero. This is accomplished by orienting the magnets so that their poles are out of phase, typically by 90 degrees. This orientation essentially re-routes the magnetic field below the […]
Conveyors with backlighting + robotics automate outlet production
Michigan-based Byrne Electrical Specialists designs and manufactures power and data technologies for office, teaching, and hospitality environments. Recently, the company began using industrial conveyors from QC Conveyors to increase their throughput of electrical outlets. A trio of robotic assembly cells — each with its own threesome of busbar conveyors and solo output conveyor — build […]
What’s the difference between cogging torque and torque ripple?
The basic operation of an electric motor relies on the interaction between the rotor’s permanent magnets and the stator’s energized windings. But even when the motor is not powered and no current is flowing though the windings, there is a magnetic attraction between the permanent magnets of the rotor and the ferromagnetic teeth of the […]
Severe duty motors: What makes them suitable for harsh applications?
While there is no broad standard that defines severe duty motors, the IEEE 841-2009 standard, which addresses “premium efficiency, severe duty, totally enclosed fan-cooled (TEFC), squirrel-cage induction motors — up to and including 370 KW (500 hp),” is often used as a benchmark. However, this standard was written for the petroleum and chemical industries, and many […]
Portescap 22ECT35 and 22ECT48 Ultra EC brushless motors for high torque from compact designs
Portescap will be offering two more new length sizes under its ECT range of Ultra EC Brushless Slotless motors — the 35mm 22ECT35 and the 48 mm 22ECT48. These new 22ECT motors along with higher torque capacity are light in weight and come in a compact package which helps in more miniaturization of the customer application. […]
Allied Motion debuts Globe Line of mil-spec PMDC motors, planetary gearmotors
Allied Motion Technologies announces the Globe line of mil-spec-qualified fractional horsepower PMDC motors and gear motors. These motors are available off-the-shelf or on short lead time through Allied’s QuickShip program. Modified versions – with specially machined mounting provisions, holding brakes, tachometers and/or encoders – are available within two to three weeks through Allied’s QuickMod program. […]
