The other side is used as a comparator to compare the amplified current sense voltage to a reference voltage. This lathe is relatively uncommon compared to the ubiquitous Seig C2, making it difficult to find information about it online. This voltage is very small (<0.5V), which is why the amplifier is necessary. Router speed control on Jet mini-lathe. High/low speed shifter 2. Compatible with a variety of mini lathes and mini mills, this speed control potentiometer is equipped with switch contacts. Onetouch ( Log Out /  I tried once more to fire up the motor, but alas A001 was staring back at me again. This IC both isolates the microcontroller from the high voltage MOSFET and switches the MOSFET with a higher voltage and current than the microcontroller could. The best lathes should come with variable speed control features. While the power of my lathe is adequate, I wouldn't mind a little more torque This IC both isolates the microcontroller from the high voltage MOSFET and switches the MOSFET with a higher voltage and current than the microcontroller could. I also noticed that the input from the microcontroller went to two pins each. This was rather lucky, as I could not find a pdf of this online despite using all my google-fu. Based on the data sheet, the pinout didn’t match exactly, but it was close. When the controller turned on I was greeted with a green LED and no red OP LED! This allows the motor run at a slow speed while still providing sufficient torque. This high quality high accuracy precision lathe is designed for model engineers’ use in the home workshop, repair workshop or schools. The spindle motor would start after pressing the forward or reverse buttons. There’s also a large diode mounted to the same heatsink as the MOSFET. Pulse width modulation (PWM) is a way to control the speed of a motor by sending short pulses of a constant voltage, rather than raising or lowering the voltage. The logic board returns a PWM signal and two relay control lines. I found the data sheets for the IC’s and located the Vcc pins for each. Steel. All rights reserved. 1.
