The new NEMA 23 Stepper Motors from Sanyo Denki were developed with high torque, low noise, and energy saving in mind

SANMOTION F2 Stepper Motor Series - 56 mm sq. 2-phase stepper motors

May 25, 2021

SANYO DENKI CO., LTD. has developed the SANMOTION F2 56 mm sq. 2-phase stepping motors, expanding the product lineup of the series.
The new models achieve best-in-class(1) torque performance and high efficiency, therefore improving machine speed and contributing to energy savings.

F2 NEMA23 Stepper Motors

Features

1. High Torque

Compared to our conventional model, torque performance has improved by approximately 40%.(2)
This contributes to shortening the positioning time and machine cycle time.

2. Low Noise

These motors have noise levels approximately 3 dB lower than the current model, reducing the noise level of machines.(2)

3. Energy Saving

Motor efficiency has been improved by approximately 3% compared to the current model.(2)
This contributes to reducing power consumption of machines and the motor’s heat dissipation.

(1) Based on our own research as of May 25, 2021, conducted among equally sized industrial 2-phase stepping motors on the market.

(2) A comparison between our current model 103H7123-5840 and new model SM2562C30B41.
