SINGLE SPEED AC/DCMOTOR DRIVE

Single Speed Motor Drives are the most economical motor drives offered and can be used in positioning applications where accuracy is not critical. Drives are available in AC or DC, from fractional hp to 3 hp, and are typically direct coupled to the ballscrew or feedscrew. The drive can befurnished with a torque limiting coupling to preventoverload damage to the motor. Traverse rates from 0.005 to 600 ipm can be provided, with proper selection of a gear box and various gear ratios (for extremely low feed rates).

VARIABLE SPEED AC/DCMOTOR DRIVE

Variable Speed Motor Drives use the same motoras a ‘Single Speed AC/Dc motor manufacturer Drive’(above), with the addition of a speed control device for varying the slide traverse rate. The speed control device for an Industrial ac drive is a frequency inverter which typically allows a 6:1 speed range. In Dc drive systems, the speed control device is a Dc controller which allows approximately a 20:1 speed range.

LOW FRICTION BEARING MATERIAL

(Model Code:T)

This self-lubricating bearing material is bound to the gib and saddle way surfaces to reduce the effects of friction on the slide assembly. Low-friction minimizes “stick-slip”, and makes wear negligible on both sliding surfaces.The application of low-friction doubles the load carryingcapacity of a slide. The co-efficient of friction with low-friction is 0.10; this drops to 0.05 when combined with a forced lubrication system. (When neither is used, the co-efficient of friction is 0.30.)Low-friction material is recommended for high speed, high duty cycle applications, and in vertical applications where overhung load conditions exist. 20
