High Quality, Low Cost Drivers for 2 Phase Steppers in OEM Applications

Santa Clara, CA - A high quality, low cost, driver for 2 phase bipolar steppers is the answer to the OEM's question, "build or buy?".

Source Engineering, Inc. of Santa Clara, CA is now able to meet the needs of OEMs with a compact driver capable of microstepping, and measuring just 2.95 in. (75 mm) x 4.96 in. (126 mm) x 1.26 in. (32 mm). The driver has been designed for NEMA 14 through 34 steppers, requiring up to 4 amps per phase and 40 VDC. They are ideal for pick-and-place, medical testing equipment, robotics, toys and games, semiconductor manufacturing, security applications, and assembly operations.

The input voltage for these drivers is 20 to 40 VDC (50 VDC absolute max). A potentiometer is used to adjust the running current. The idle current is 50% of the running current and is activated in 0.5 sec after the last pulse. These drivers can also be used for microstepping. Dip Switch settings provide microsteps of 2, 5, 10, 16, 20, 32, 40, and 64 steps-per-step. Fully enclosed, the driver is mounted on an integral heatsink, and all connections are easily made with terminal blocks for easy integration into new and existing applications.

Also available from Source Engineering are high quality, low cost 2 phase bipolar steppers and gearmotors.

Source Engineering, Inc. located in Santa Clara, CA is a also supplier of brushless and brush-type motors, stepper motors, induction motors, optical encoders, gear boxes, gearmotors, amplifiers, universal power supplies, optical lenses, cable harnesses, and molded cables, and reflectors to OEM's.
