Installation of a Hitachi WJ VFD and changes to the control switches on a PMGT lathe. The lathe was purchase as a 3 phase unit, the stock 3 phase motor was retained. The Jiuh Dah Electric Taiwan 2 HP motor is not inverter rated, the nameplate indicates it is V, 60Hz, 6. The motor is not large, and is a tight fit. There is only 1" between the back motor fan guard and the lathe splash guard, and the motor diameter limits the belt adjustment range. Those interested in a possible inverter rated replacement motor, might look at the 2 HP Leeson True Metric D90L or the Marathon version LT17FH which looks identical. Both of these have 24x50 mm shafts, so the stock pulley would need to be bored or replace it with a different one. Replacement 2 HP vector rated motors I checked where too long to fit without cutting off the rear shaft. That being said, most 2 HP inverter rated motors have a constant torque ratio of at leastand have a useable maximum RPM of 1. TEFC fan cooled motors are limited at slow or high speeds by the fan cooling capacity. I currently use the stock motor over a VFD frequency range of Hz, so a usable lathe RPM range would be around Using the vector motor VFD settingthere is no cogging even at very low speeds, Lathe installation hitachi wj200 inverter url am adding a digital RPM meter to provide the lathe readout speed. So on to adding the Hitachi WJ inverter. Usually I hardwire the Lathe installation hitachi wj200 inverter url controls directly to the inverter with shielded cable, and use limiter switches and a safety stop switch. In the case of the PMGT, I decided to have a bit more complex switch logic with safety interlocks.
