I have a Pacific Scientific R46GENA DC brushless servo motor that I would like to use for my Bridgeport conversion, so I am looking for a amp/driver to drive it.
The specifications are on page 26 here: http://www.pacsci.com/support/documents/pc800/svomtrs.pdf I don't know if it is a sinusoidal or trapezoidal motor so if anyone has a way to determine this, please let me know. Is the difference in the drive just software? The specifications indicate an RPM of 1,700 at 240 Vac, 320 Vdc and 16.5 Amps max., so I assume that I need a 320 Vdc 20 Amp motor supply? The motor has only Hall sensors. Do the Hall sensors have an analog output in order to be able to position the rotor at a desired angle from the sensors? Could the Pico Systems PWM brushless amp be used as a basis for my application? In other words, could I change the power components to higher voltage/current? Is a continuous stall torque of 7.6 Nm (67.3 lb*in), and a peak torque of 20.2 Nm (179 lb*in) appropriate for a Bridgeport? My plan is to have a direct coupling between the motor and ballscrew. I have some Sanyo P5's but at 3.9 Nm (46 lb*in) continuous and 11.7 Nm (139 lb*in) peak torque, but they seem a little small. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe Bridgeport mill conversion pending Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
