Multiple prevention measures required for failures due to momentary stops

While producing automobile parts outside Japan has become the mainstream, supply of power to run machines in overseas is still unstable compared to Japan. Countermeasures such as uninterruptible power system (UPS) have been in use to cope with the problem. Even so, if a machine such as grinding machine stops suddenly, rotational energy of grind stone does remains due to the weight of grind stone. This could damage the motor or other mechanical parts. Because of these issues, manufacturers of machine tools, especially of grinding machines, have provided measures to cope with momentary stops to their machines, and the measures need to be effective and more than just one.
