Motor Controller Provides Custom Electronic Control Solution

A Fortune 200 company needed a turnkey, DC voltage, agency-compliant electronic control solution capable of providing motion control with memory position capabilities and auto run/sense features for a multi-motor application involving four motors. Particularly important to the design criteria was the development of an interactive system of wireless remote control capabilities and other user interface devices, including iPhone and iPad interconnect devices. It was a complicated job, and the company would need to partner with experts who could deliver a time- and cost-effective solution.

Servo Drives

Advanced Motion Controls® (Camarillo, CA) announced AxCent™ servo drives for centralized motion control schemes. The Models AB15A100, AB25A100, and AB20A200 are panel-mount servo drives that operate with brushless permanent magnet motors as well as brushed motors and inductive loads. The drives are controlled with ±10V analog command signals, and use trapezoidal commutation when driving brushless motors. The AB15A100 outputs 15A peak and 7.5A continuous with up to an 80VDC bus; the AB25A100 outputs 25A peak and 12.5A continuous with up to an 80VDC bus; and the AB20A200 outputs 20A peak and 10A continuous with up to a 175VDC bus.

Brush DC Mini Motors

Portescap (West Chester, PA) introduced the 16DCP Athlonix™ high-power-density brush DC mini motors. Available in a 16-mm diameter, the 16DCP motors feature a coreless design with an optimized self-supporting coil and magnetic circuit. The motors are available in two variations — precious metal commutation and graphite commutation — both featuring an Alnico magnet inside. The motors feature a constant force spring design for carbon brush, and an REE (Restriction of Electro Erosion) coil is an available option. With maximum continuous torque up to 2.63 mNm, the motors are suited for medical and industrial pumps, gas analyzers, security and access, and power tools. They are available with encoders and gearheads of various sizes and ratios.

Modular Drives

Control Techniques, a business of Emerson Industrial Automation USA LLC (Eden Prairie, MN), offers Unidrive M and Powerdrive F300 variable-speed, high-power modular drives. Both are available in frame size 11, providing a flexible method of building compact, high-power solutions. Paralleled together, Unidrive M can control asynchronous and permanent magnet motors in systems up to 2.8 MW (4,200 hp). The frame 11 is a 250-kW (400 hp) module that allows system builders to create high-power solutions with a small number of components. Unidrive M’s Active Front End (AFE) solutions provide torque precision and power quality.

Permanent Magnet Motors

NovaTorque (Fremont, CA) introduced 600 RPM versions of its PremiumPlus+® Electronically Commutated Permanent Magnet (ECPM) motors. The new versions are available from 0.75 HP to 3 HP, and are suited for directly driving larger-diameter fans at low speeds. The motors offer lower current requirements (FLA) than AC induction motor alternatives. A patented geometry allows for the use of readily available ferrite (versus rare earth) magnets. The motors are produced in standard NEMA frame sizes.

Variable Frequency Drive

American Control Electronics (South Beloit, IL) introduced the ACF Series of open chassis microprocessor-based variable frequency drives that offers the simplicity of a DC drive. ACF700 drives are designed for setup without any programming. The drives are equipped with user-adjustable trim pots to set Max/Min Speeds, Slip Comp, Boost, Torque Limit, Accel, and Decel/Injection Braking parameters. The 115V/230V single-phase input can provide single- or three-phase outputs of 115V or 230V for sub-fractional HP motors and gearmotors. An onboard microprocessor allows custom programming for a variety of OEM applications. Other features include 1/60 to 1 HP, carrier frequency of 1.6 or 16 kHz, adjustable base frequency, DC injection braking, and protection against overheating as a result of frequent overload.

Servomotors

Siemens Industry (Elk Grove Village, IL) offers Simotics 1FK7 Generation II servomotors with seven shaft heights, quick-connect power connectors, and 20- and 24-bit field-replaceable encoders. The series offers three inertia versions — standard, high-dynamic for rapid acceleration jobs, and high-inertia for maximum smooth running. The motors are designed for operation without external cooling; heat is dissipated through the motor surface. The encoders are mechanically and thermally decoupled from the motor, making them more resistant to vibration conditions on the machine. The servomotors provide cross-profiling for mounting, Drive-Cliq interface for field commissioning and unit recognition with the Siemens Sinamics S120 drive family, plain shaft or keyway design, and three IP ratings.
