M.LX Motor: These permanent magnet motors are specifically designed for high torque/low speed applications, offering more power for jobs like stone setting, wax modeling, and pearl drilling. M.LX ball bearing motors feature full power and torque from start up and throughout the entire speed range up to 5,000 rpm. They are ideal for use with Foredom drill presses. They also are well matched with the H.15 and H.15D Hammer Handpieces. It comes equipped with a motor bale for hanging, and Foredom's standard 39? long key tip shafting for connecting to any of Foredom’s key tip handpieces. Foredom’s permanent magnet motors require the use of a TXR-1, SXR-1, or EMX-1 speed control. These controls have the same housing as other Foredom speed controls but they convert AC current from an electrical outlet to DC current required by Series LX motors. These controls have a different style plug that is made to fit the motor’s shielded-type plug. Damage will result if the motor is connected to any other speed control. C.TXR-1 Speed Control foot operated speed control is made of heavy duty plastic with durable solid state electronics. The ergonomics allow precise and reliable speed control with your foot. For use with 115 Volt M.TX, M.TXB, M.TXH, M.LX, M.LXB, M.LXH and M.LXBH motors. 7? long, 4-12? wide, 2-38? high, ship wt 2 lbs./1 kg.
