1. Introduction
Stepping systems are widely used as actuators for
sem ic onduc tor manu fact u r i ng e qu ipment, of f ice
automation equipment, and food machinery, with their
reasonable system costs and their ease of open-loop
control. SANYO DENKI developed and marketed new
pentagon winding-compliant 5-phase stepping system
in 2006. Currently, the market demands a driver with
micro-step driving function installed in it for further noise
reduction and vibration.
In response to the demand, SANYO DENKI newly
developed “SANMOTION F5”-series model micro-step
driving 5-phase stepping driver.
This report describes the overview and features.
2. Product Overview
Figure 1 shows the appearance of the new model.
We constructed the model of low on-resistance surface
mount type FET for the power device aiming to release the
heat to the heatsink. This suppressed heat generation and
managed to limit the product height to 28 mm.

3.2 Low-vibration
Micro-step driving function is a method to divide motor
primary stepping angle by controlling current at each
phase in incremental steps without using mechanical
devices. This is fundamental function to reduce machine
vibration and for subtle positioning. The new model
achieved to create ideal motor current by detecting and
controlling winding current at each phase controlling in
addition to install this function. This greatly suppressed
velocity fluctuation compared to the conventional model
with micro-step driving function installed in it.
Figure 4 shows velocity fluctuation characteristics
compared to the conventional model.
Stepping motor has a disadvantage that the vibration
caused by step-driving at low velocity increases. This
vibration becomes greater especially when command
resolution is low. The new model installs low-vibration
mode function to modify the vibration issue. This function
enables the driver to smoothly operate with micro-step
3. Features
3.1 Small-sized and light-weighted
Downsizing and weight saving for the new model
have been achieved with miniature parts and optimized
heatsink fin shape (new model-to-DC 48 V-compliant
model volume ratio is 45%, the mass has been reduced by
8% of the one of DC 48 V-compliant model.).
Figure 3 shows new model-to-convention model volume
comparison.
