Overview
The Philips 9904 111 32803 is a compact synchronous AC motor designed for direct-drive, low-speed applications in industrial control and instrumentation. Operating at 250-300 RPM across 50-60Hz supply frequencies at 24V, this motor provides consistent, predictable rotation for timing-critical processes. The Philips 9904 series represents a proven line of synchronous motors widely used in European industrial equipment, including Ultramat 23 source models and comparable diagnostic and analytical instruments.
Key Features
- Synchronous AC motor design ensures frequency-locked, constant-speed operation
- 250-300 RPM output suitable for direct-drive timing applications without gearing
- Compact, sealed ovoid housing design fits space-constrained installations
- Reversible rotation capability with dual-phase winding configuration
- Low power consumption and inherently quiet operation
- Direct AC supply connection; minimal support components required
