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

SANMOTION R 3E Model

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.

SANMOTION R 3E Model

Features

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.
