Servo motor compaired to Sailrite MC-SCR Sewing Machine Motor
Servo sewing machine motors are promoted strongly, but the truth is that they are weak performers at slow speeds in medium to heavy weight materials. Watch this video and see the servo motor verses the Sailrite MC-SCR motor. There is no comparison. Sailrites MC-SCR power system beats the servo motor for slow speed control and power.
How to Install the MC-SCR to a Sewing Machine Table
NOTE: Sewing machine configurations and table tops vary! Please check your measurements for the correct mounting position prior to drilling into your table top. To do this install the balance wheel and the motor's pulley on the sewing machine and motor. Place the belt on the balance wheel and run it to the motor pulley to determine the correct motor mounting position for the motor bracket.
