Customizable items (examples)

• Gear head
• Lead pin
• Grounding terminal
• Ball bearing (available for some sub-models)
• Lead wire variants

Notes
Some sub-models vary in length, applied voltage and internal resistance to achieve different speed, torque and efficiency trade-offs. The series covers a broad performance range from low-voltage, compact fan motors to higher-voltage, higher-output variants.
