Flexible Magnetic Position Sensor
iC-Haus (Naperville, IL) has announced the iC-MH16, a one-chip
solution for magnetic sensor applications in fast motor control units.
Combined with a diametrically magnetized permanent magnet, the
device in a QFN28 5 x 5 mm package can be used to create a universal
encoder for motor commutation and positioning. Features include:
n A Hall sensor array with signal amplification control.
n A FlexCount interpolator delivering incremental (ABZ) and latency-free
commutation (UVW) signals.
n Integrated RS422 line drivers.
n A serial SSI/BiSS interface.
n An incremental edge rate of 16 MHz.
n A rotation speed of up to 200,000 RPM.
n UVW commutation signals available for
any pole pair count ranging from 1 to 16.
n A supply voltage of + 5 V (±10%).
n An operating temperature range from -40° to +125°C.
Rigid Shaft Couplings & Shaft Adapters
Stafford Manufacturing (Wilmington, MA) has announced
a full line of rigid shaft couplings and shaft adapters for OEM
and MRO applications. Stafford Rigid Shaft Couplings &
Shaft Adapters are designed to join shafts of different sizes
and configurations, extend shafts, and provide different mating
options. Features include:
n Availability in a variety of configurations made from steel,
stainless steel, aluminum, and brass.
n Rigid shaft couplings available in one-, two-, and three-
piece designs with or without keyways.
n Shaft adapters offered in step-up and -down configurations
with or without keyways.
n Shaft extensions, which can be round, square, hex, D,
threaded, keyed, and tapered.
2,400 RPM Permanent
Magnet EC Motor
Nova Torque (Fremont, CA) has introduced
2,400 RPM versions of its 3 to 15 hp models,
with rated efficiencies of 93.5 to 95%. In
many cases, the motor will be one full frame
size smaller than the alternative AC induction
motor, reducing weight, cost, and possibly
VFD size. Features include:
n A 30 to 50% reduction in motor losses
and 5 to 20% reduction in energy usage
when compared with NEMA Premium
n Compatibility with all leading VFD brands.
n Production in NEMA dimensions.
n An all-ferrite (versus rare earth) magnet
