Subject: [Test Equipment Design & Construction] Stepper Motor info needed for an Antenna Tuner project.? Hi everyone, im in the process of designing and building an automatic antenna tuner using some large variable caps. These are attached to Stepper motors for which i have no info. The motors are Philips 400mN/M 1.8 deg. Marked with the following numbers which i assume are part numbers :- 9904? 115? 23101 MB21? 4386 Ive tried searching for data on these motors without success, and i understand Philips no longer make stepper motors. Has anyone got any datasheets or an old data book with the info please Kind regards? Pete
