Industrial sewing machines require much more powerful motors than domestic (home) machines, both for speed and the torque to power heavy duty mechanisms through various fabrics and skins. There are basically two types of motor used in industrial sewing machines: clutch and servo.

Clutch motors, preferred by garment and canvas sewers, weigh about 40 pounds and are meant to operate at full speed. One must be able to "feather the clutch" to sew slowly. The motor portion runs all the time it is powered on and they generate heat and eat up electricity.

Electronically controlled servo motors, preferred by leather crafters and holster makers, only consume power as they drive the machine and have more granular slow speed control than most clutch motors. Since the motor is not turning until you engage it, there is almost no heat generated or power consumed unless it is being actively used. They are also much lighter than clutch motors.

Toledo Industrial Sewing Machines stocks a variety of industrial sewing machine clutch and servo motors, including the much sought after Consew Premier CSM550-1 servo motor, described on the right.

Speed Reducers

Two styles of speed reducers for industrial sewing machines

Sometimes you may want to slow down your motor even more than the smallest pulley allows. Some servo motors lose torque (and punching power) at very slow running speeds. A speed reducer between the motor and machine can both slow down the motor and multiply its punching power by the same ratio.

We currently carry two types of speed reducers, as shown in the photo on the left: a new box type which we sell for $200* and a 3 pulley model SR-2, selling for $150*. The box-style is used on flatbed machines that set in the table. It will allow you to tilt that machine back easily for oiling underneath. The SR-2 is used on cylinder arm machines where there's limited space.

When adding a box style reducer you may possibly need to drill new holes in the table to get the reducer pulley to line up with the machine pulley. (This doesn't happen too often). You will also have to measure around the pullies and obtain 2 new Type 3L belts (the width is 3/8"). You can buy them locally at a hardware or auto parts store, or order them from us.

When changing from a clutch motor to a servo, you may require a shorter belt. You will have to determine belt lengths after installation. Again, we do supply belts but they are standard 3/8" (Type 3L) that can be obtained at a hardware or auto parts store.

*The speed reducer prices do not include shipping charges.
