SANMOTION F2 42 mm sq. 2-Phase Stepping Motors
Ideal for applications in devices such as ATM and medical inspection equipment

October 31, 2017

SANYO DENKI CO., LTD. has developed 42 mm sq. 2-phase stepping motors, expanding the product lineup of the SANMOTION F2 series.

With improved holding torque* and reduced noise and vibration, these motors demonstrate industry-leading performance** among stepping motors used in devices such as ATM and medical inspection equipment.



1. Shortens positioning time

Holding torque has been increased approximately by 10% compared with our current model.***
This enables precise positioning and thereby shortens positioning time as well.

2. Reduced noise

These motors have noise levels approximately 3 dB(A) lower than the current model.***

3. Energy-saving

Motor efficiency has been improved by 2.4% compared with the current model.***
This contributes to reducing power consumption of devices and the motors’ heat dissipation.

* The maximum amount of torque generated when a stepping motor is excited by its rated current.

** Based on our own research as of October 31, 2017, conducted among equally sized industrial 2-phase stepping motors on the market.

*** A comparison between our current model 103H5208-0440 and new model SF2422-12U41.
