Servo Motors Selections – Making The Right Choice

[secondcrk]

The first one I bought went through 3 sets in a year and a half. Plus its one less thin to worry about

can you elaborate on the advantage of the brushless servos please? (besides the fact that brushes wear). thanks.

My choice of motor.

It does not matter if you have a great sewing machine if the motor is a piece of #%#&.

The motor is as important to a sewing machine as it is for a car.

I desided to take the step in to the 21st century and buy a professional motor for my TSC 441 clone.

It had a clutch motor and a speed reducer, I changed these out for a Efka DC 1550 ( with a 321 control).

First I thought I needed the speed reducer, but no. These motors are made to power any kind of sewing machine without any help from reductions gears. The nominal power is 600w, if more is needed just turn it up. It delivers max 1800 watt and a torque of 8 Nm (thats enough for any sewing application). It has needle position and is programable for all kind of stitch patterns (backtacking etc).

You can attach all kinds of solenoids (24 should be enough I think, I am only using one for a pneumatic foot lift) and your computer too. (the control box is a computer, you can change everything or just plug in a memory stick and be ready to sew, certain sewing machines the motor will recognize, plug and play, and every parameter are set automatically)

The low speed control is great. But the best of all, no matter where you bought it you will get support from EFKA Germany if you need it. I received Skype video-call support on programming it from them.

Thank you Manfred with Efka;

Down sides: you pay a bit more for this motor. Avantages; no need for a speed reducer, very small motor can be placed on the machine head, the best quality and world wide support, a true professional motor drive with the best preformance and low speed control.

With other words; No bullshit. http://www.efka.net/en/Aktuelles/aktuelles.htm
