BX series power ratings and listed input power

Postby jwyoungster » Sun Aug 31, 2014 6:00 am

can someone explain to me the numbers on the BX series datasheets:

example:
bx6200...running continuous flat torque speed...3000rpm....continuous torque it delivers is .65Nm....works out to 200W....(just like the data sheet says...200W drive)

why oh why does the data sheet say that for the 100V model bx6200, rated current capacity is 4.7A????????
is it a 200W drive with lousy efficiency?....
can someone explain these numbers?......
trying to size a power supply for this thing...

Hi jwyoungster,

Due to the power factor of AC circuit products, the input power (V x I) will appear greater than the actual input power. We recommend that you measure with a power meter for a more accurate reading. The efficiency rating for the BX series motor and driver system is actually around 82% (200W output/245W input).

We recommend sizing a power supply that's rated for the maximum input current instead of the rated input current. When our BX motor system encounters an overload condition, it will draw more current in order to increase its torque output to overcome the load torque for a limited duration. If the system never encounters overload, then it should be operating at its rated current.
