This inverter drive reduces speeds down to 16rpm, and offers a very smooth power transmission.

For the WMT300 lathe, also compatible with the WMT500.

Speed comarison:

Standard machine           Variable speed machine
chuck speeds                   chuck speeds
160                                      16 - 192
250                                      25 - 300
400                                      40 - 480
630                                      63 - 756
1000                                   100 - 1200
1600                                   160 - 1920

Full torque is maintained.

Available as a kit for customer fitting. Parts include inverter drive, switch control panel with stop, start, forward, reverse and jog, 24 volt low voltage transformer wiring diagram. Fitting time approximately 1.5 hours.

It is necessary to change the existing 1 phase motor to a 3 phase 240 volt = which, when connected to the inverter will operate from a 13amp plug on a domestic single phase power supply. The replacement motor is the same frame size as the original unit and will, therefore, fit directly to the existing mounting. See item no. 307003A.
