ThinGap Motor Technologies has announced the new TG3600 Series half-horsepower
slotless brushless DC servo motor utilizing a new winding technology without
wire windings that eliminate eddy current, hysteresis losses and cogging
(patent pending). The NEMA 23 size TG3600 delivers exceptional power density,
high torque to weight ratios and flat torque output at from one revolution
per day up to 4,500 RPM, which in many applications can be used to eliminate
the cost, weight and space of a gearbox.
"Our TG3600 utilizes a revolutionary new motor winding technology
that delivers power density of 100 ounce-inches per pound enabling our
customers to build lighter more powerful products," said Jerry Yankie,
president, ThinGap Motor Technologies.
The ThinGap technology eliminates magnet wire and iron laminations in
the stator while incorporating a rotor containing the entire magnetic
circuit as it rotates, eliminating positioning errors and power loss caused
by hysteresis, cogging torque and radial deflection. In combination with
high-energy neodymium-iron-boron magnets, the thin wall of the stator
coil allows a miniature air gap to create a high power density brushless
motor.
delivers maximum continuous torque of 120 ounce-inches at 2,450 RPM rated
speed using an input voltage of 24 VDC and 15.6 amps to the motor from
the specified PWM servo amplifier. Armature inductance measures below
10 microhenries and line-to-line resistance is 300 milli-ohms @ 25°C.
The TG3600 series is thermally rated for high performance operation at
up to 160°C. Unit size measures 2.240 inches OD by 2.258 inches long.
The ThinGap TG3600 Series brushless motor is useful for applications including
air bearing spindles, wafer handling, medical instrumentation, material
handling, machine tools, factory automation, packaging and even fuel cells.
