Santa Clara, CA—December 2005—Lin Engineering, the Step Motor Specialists, are pleased to introduce the new SilverPak 23DE; an integrated Nema 23, High Torque, 1.8° bipolar step motor, microstepping driver and encoder. The SilverPak 23DE is designed to help reduce overall design time and system cost for a wide array of step motor applications needing high torque.

The SilverPak 23DE is 2.25” in width and is offered in three body lengths: 2.52”, 2.96” and 3.89”. Depending on its stack size, the integrated motor/ driver is capable of producing up to 294 oz-in of holding torque. The SilverPak 23DE operates from 15 VDC to 48 VDC and the available phase current ranges from 0.3 Amps to 3 Amps peak. This integrated motor/driver combination boasts jumper configurable step resolutions ranging from 2x microstepping up to 256X microstepping and 4 selectable damping modes. The unit also features: optically isolated step, direction and disable/enable inputs; as well as under-voltage and over-temperature protection. Pole Damping Technology™ (PDT) is yet another feature that the SilverPak 23DE is capable of. Pole Damping Technology enhances step motor performance, thus creating a more accurate and smooth motion profile.

The following features/options are available with the built-in encoder:

Tracks up to 100,000 cycles/sec

32 to 1250 CPR

Max 5000 pps

2 channel quadrature TTL squarewave single ended outputs and optional index
(3 rd channel).
