The speed and up/down needle position are easily adjustable
Jack JK-513c Servo motor dynamo Reduces Power Consumption and is more energy-efficient because the dynamo automatically stops when the sewing pedal is released.
In the standby position, the electricity used is only 4 Watts (Ordinary Dynamo/Clutch Motor will consume around 180 Watts of electricity when not in use)
The speed of the Dynamo Servo can be adjusted without changing the engine pulley, and maintenance will be easier because the user does not need to replace the canvas, etc.
