Leadscrew Systems

Leadscrew systems - less revolutions per minute, less wear.

ECOSTEP®: "How would you make a stroke of 1 m in 1 second and 100 mm within a fraction of a second with 40 kg linear load without a gear?" - Potential buyer: "I would take an AC Servo, size 115 x115 x185 mm³ with 3.5 Nm nominal torque at 3000 rpm and a lead screw with 20 mm lead."

ECOSTEP®: "Ok that's what I expected, but have you thought that the screw will wear down faster at such high speeds? If you take our 42S90, you could take a screw with longer lead of 50 mm and make the same but at half speed - wouldn't that be more economical at the same performance?" - Potential buyer: "I just believe what I've seen. What do I need exactly?"

ECOSTEP®: "You need the motor 42S90, the amplifier-controller ECOSTEP®216-AA, the rectifier ECOBRAX200-BA plus a transformator TD1500-85/105 for 1-3 motors." - Potential buyer: "That's a lot of equipment for one electrical drive system - my AC Servo system consists of a 2 KVA direct amplifier with controller and the motor."

ECOSTEP®: "Ok we divided the direct amplifier into three parts that cost together the same. On the other hand this gives you a price benefit if you use more than one amplifier in that circuit." - Potential buyer: "Ok ... ."
