Overview
The Superior Electric M093-FD11 is a precision NEMA 34-frame SLO-SYN stepper motor engineered for demanding industrial motion control and positioning applications. This rugged synchronous stepping motor combines exceptional holding torque with flexible electrical configuration, making it a trusted choice for CNC machines, manufacturing equipment, and automated systems. The M093-FD11 delivers consistent performance across unipolar and bipolar drive configurations.
Key Features
- NEMA 34 frame size (90mm) with 70mm mounting hole spacing
- 200 steps per revolution (1.8° per step)
- Reversible operation for bidirectional control
- Six-wire configuration supporting both unipolar and bipolar drive
- Class B insulation rated to 65°C
- Direct bolt-mount mechanical interface
Technical Specifications
The M093-FD11 operates efficiently across a wide range of industrial motion control scenarios. Standard unipolar configuration provides 2.7 VDC nominal supply with 5.5A per phase, delivering 450 Oz-In (31.8 N·m) minimum holding torque. Alternative bipolar configuration operates at 3.8 VDC with 3.9A per phase, offering greater dynamic performance and reduced power dissipation. Winding specifications include 0.48 ohms nominal resistance per phase and 3.2 mH inductance, enabling smooth acceleration profiles and low settling times.
