Motor Control Pre-Driver IC enables quiet low-power fan operation.
2015-02-18 14:30:40| Industrial Newsroom - All News for Today
Accommodating 3.5–30 V input, TC78B006 series comprises single-phase brushless DC (BLDC) motor control pre-driver ICs available in 5.5 x 6.4 mm SSOP16 or 3 x 3 mm QFN16 package. PWM voltage and pseudo sine-wave current driving functions promote efficient and quiet cooling fan operation in data servers and home appliances, while automatic standby function reduces power consumption when fan is not in use. Additionally, IC can drive 2 external high-side Pch and 2 low-side Nch MOSFETs.

Stepper Motor delivers smooth motion and quiet operation.
2015-02-03 14:30:40| Industrial Newsroom - All News for Today
Part of SmoothStep line, Whisper Torque ZH417-11 Stepper Motor with Signature Series Technology can incorporate up to 11 mm ID hollow shaft and still maintain accuracy and torque. NEMA 17, 0.9° motor features patent pending design that has no magnet on rotor. Instead, motor uses ring magnet around stator coils that is sandwiched between stator stack. Since there is no permanent magnet in rotor and only outer edges of rotor are used, large shaft dimensions can be implemented.
