The Technical Edge: Why Brushless?
Unlike traditional carbon brush motors, brushless systems like the VK-MM series from Shanghai Craftro Tech eliminate physical friction. This isn’t just a minor upgrade; it’s a revolution in performance:
- Consistent Torque: Traditional motors often stall under pressure at low speeds. Brushless controllers provide “Torque Compensation,” maintaining steady power whether you’re at 5,000 RPM or 50,000 RPM.
- Zero Carbon Dust: By eliminating brushes, you eliminate the carbon dust that can contaminate sensitive medical ceramic surfaces or delicate jewelry settings.
- Thermal Stability: Less friction means less heat. The handpiece stays cool during 8-hour shifts, protecting internal bearings and ensuring user comfort.
Maintenance: How to Protect Your Investment
Precision tools require professional care. To ensure your VK-MM5 or VK-MM2 lasts for years, follow these expert maintenance rules:
- Never Oil Your Handpiece: Modern brushless handpieces use sealed, pre-lubricated bearings. Adding oil will actually destroy the internal grease and attract dust.
- Avoid “Empty Runs”: Always keep a bur or test pin in the collet. Running the handpiece “empty” creates unbalanced forces that can damage the three-lobe spring.
- Keep it Clean: Use a cloth moistened with alcohol to wipe the exterior daily. Never submerge the unit in liquid.
FAQ
Can I use my existing burs with Craftro micromotors?
Yes, our units are compatible with standard 2.35mm shank diameter burs. For the best results and lowest vibration, always ensure your burs are high-quality and balanced.
How long does the battery last on the VK-MM5?
The VK-MM5 features a 2600mAh high-capacity battery that supports up to 9 hours of continuous operation on a single 3.5-hour charge.
Why is my handpiece getting warm during use?
While brushless motors generate less heat, some warmth is normal during high-speed operation. However, if it becomes too hot to hold, check if the collet is clogged with debris or if you are applying excessive pressure.
What certifications does Shanghai Craftro Tech have?
We are a national high-tech enterprise certified under ISO13485, MDSAP, and FDA. Our products also comply with CE, FCC, and ROHS standards.
