I'm trying to find the correct motor for a project we are building - but I'm confused how to read the RPM from the nameplate.

As you can see there are 2 different RPMs listed on the plate. Which one should normally apply? We are using 230v supply.

Many thanks for you help,

that is a nameplate of a gearmotor meant to operate at 50Hz. so the motor speed 1410RPM, gearbox output is 37RPM suggesting gear ratio is 38.1:1

Given the ratio of the speeds given, 57 RPM and 1.41 RPM?it seems that it may be a dual output gear box. OR that may be the actual ratio: 37/1.41. But that does not seem reasonable.
