Product Overview
The Sun Star B14 face mounted motor features a compact flange on the drive end with threaded bolt holes. The driven equipment is bolted directly to the motor face using bolts that thread into the motor's tapped flange holes. A precision spigot (centering register) ensures accurate shaft centering.

Common Applications
Industries Served
OEM Machine Builders
Compact motor drive for machine tools, pump assemblies, and specialised equipment manufactured by OEMs.
HVAC
Axial fan drives, small circulation pumps, and compact ventilation systems.
Textile Industry
Compact motor drives for winding machines, bobbin winders, and textile processing auxiliaries.
Key Benefits
- Compact flange design saves space in machinery with limited installation room
- Threaded bolt holes simplify installation — bolt the machine directly onto the motor
- Precision spigot ensures perfect centering without separate alignment procedures
Why Choose Our Motors
- B14 flange with threaded holes and precision spigot for accurate, easy installation
- Both aluminium and cast iron body options available
Manufacturing & Quality
Manufacturing Process
Face mounted motor production includes CNC machining of the B14 flange with threaded bolt holes. The spigot diameter is machined to IEC tolerance and verified for concentricity.
Quality Standards
- Spigot concentricity verified to IEC tolerance
- Thread quality checked with go/no-go gauges
- Standard motor testing (IR, HV, no-load, vibration)
Certifications
Selection Guide
Choose B14 face mounting when the driven equipment has a matching B14 flange interface. This is most common in small pumps (up to 7.5 HP), axial fans, and OEM machine tool applications.
Comparison With Similar Motors
| Feature | Sun Star Motors™ | Typical Market Motor |
|---|---|---|
| Flange Type | B14 with threaded blind holes | Same for B14 standard |
| Spigot Accuracy | CNC-machined to IEC tolerance | Conventional machining |
| Body Options | Aluminium and cast iron | Aluminium only in most cases |
| Voltage Options | 415V and 230V available | 415V only in many cases |
Installation Guidelines
- Verify that the driven equipment's mounting holes match the motor's B14 bolt circle dimensions
- Apply threadlocker compound to the mounting bolts to prevent loosening under vibration
Maintenance Tips
- Check mounting bolt torque every 6 months — threadlocker compound degrades over time under vibration
- Inspect the spigot fit during any dismantling — wear in the spigot allows misalignment
- Follow standard motor maintenance schedule for bearings and insulation
Troubleshooting Guide
| Issue | Possible Cause | Solution |
|---|---|---|
| Motor bolts do not fit the driven equipment | Equipment uses B5 (through-hole flange) instead of B14 (threaded face mount) | Verify the mounting type. B14 has threaded blind holes; B5 has through holes with a larger flange. Replace motor with correct mounting type. |
| Vibration at motor-machine interface | Spigot worn or damaged, mounting bolts insufficient torque, or threadlocker failed | Inspect spigot. Retighten all bolts with fresh threadlocker. If spigot is worn beyond tolerance, replace motor. |
