The Series H39Y from Thomson Airpax Mechatronics is a new high-torque 39mm hybrid step motor.
The Series H39Y from Thomson Airpax Mechatronics is a new high-torque 39mm hybrid step motor.
Improved performance and competitive pricing make this motor ideal for 39mm (Nema 16) applications, and for replacing 42mm (NEMA 17) with a smaller motor.
The 1.8-degree step motors - measuring 39mm square - are available in four motor lengths: 20, 34, 38, and 44mm.
These high efficiency motors come in both unipolar and bipolar versions, have a holding torque range of between 63 and 284mNm, and weigh between 120 and 250g.
They feature a +/-5% per step, step angle accuracy, and maximum temperature rise of 80C.
This combination of high torque and small footprint makes the Series H39Y ideal for applications requiring fast acceleration as well as sustained high speed.
These include office automation/computer peripherals (printers); medical (scanners); fluid handling and industrial (pumps and test equipment), and robotics.
Consistent with Thomson Airpax Mechatronics' focus on satisfying customer needs, the 39mm Series was designed for an automated assembly friendly to modification.
Flexibility exists in accommodating different lead terminations and shaft modifications to fit most applications.
Other specifications are: current ratings from 160 to 800mA; resistance per winding between 6.6 and 40ohm; dielectric withstanding voltage of 500V AC for 1min; inductance per winding between 6.0 and 100mH; rotor moment of inertia between 11 and 40gcm2; and detent torque between 50 and 250gcm.
