What is a 2607 Coreless Motor?

The 2607 Coreless Motor is a specialized micro direct-current motor featuring a unique ironless rotor architecture. The nomenclature designates an outer diameter of approximately 26 mm and a thickness/length of around 7 mm (typically configured as an ultra-slim, flat-type profile).  

Unlike traditional motors with iron cores, coreless designs eliminate magnetic core losses, providing exceptional miniaturization and energy efficiency.  

Key Advantages & Features

• High Efficiency & Low Energy Consumption: Free from iron-core hysteresis and eddy current losses, energy conversion efficiency routinely reaches 70% to 90%+.  
• Rapid Response & Dynamic Performance: Extremely low rotor inertia ensures millisecond-level startup and braking times.  
• Zero Cogging Effect: The ironless rotor guarantees ultra-smooth rotation completely devoid of traditional cogging or stumbling at low speeds.  
• Minimal Electromagnetic Interference: Premium commutation systems reduce electrical sparking and acoustic/electromagnetic noise.  

Technical Specifications & Electrical Performance (12V Reference Example)

Specifications can vary depending on custom winding designs (compatible with standard industry standards like Faulhaber, Maxon, or XH Motor). Below are the benchmark specifications for a standard 12V flat-type 2607 coreless motor:  

1. Mechanical & Physical Dimensions

• Dimensions (Diameter × Length): 26 mm × 7 mm (Ultra-slim flat design)  
• Shaft Diameter: Standard 1.5 mm  
• Weight: Approx. 15g – 20g (Depending on housing and bearing configurations)  
• Rotor Structure: Ironless honeycomb cup rotor (Low inertia, cog-free)  
• Commutation System: High-grade precious metal brushes and commutator (Long operational life)

3. Dynamic & Control Characteristics

• Mechanical Time Constant: Superior speed response within the 6ms to 8ms range for instant start-stop execution.  
• Rotor Inertia: Extremely low (approximately 0.7 g⋅cm2), eliminating lag during rapid directional shifts.  
• Back-EMF Constant: Varies by voltage winding (e.g., ~0.9 mV/RPM for 6V; ~3.8 mV/RPM for 24V), ideal for closed-loop precision speed tracking.  
• Terminal Resistance: Ranges from single digits (e.g., ~8 Ω for 6V variants) up to over 100 Ω for higher-voltage models.  

Target Application Fields

Because the 2607 motor combines ultra-low profiles with heavy-duty torque density, it drives cutting-edge portable and handheld technologies:  

1. Tattoo Pens & Machines: 2607 and 2610 flat coreless motors serve as the powerhouse core for professional rotary tattoo devices, offering low-vibration, high-endurance performance.  
2. Precision Medical & Beauty Equipment: Integrated into micro-infusion pumps, fluidic devices, and high-frequency cleansing instruments.  
3. Smart Hardware & Micro-Gimbals: Tailored for ultra-compact servomechanisms, camera stabilization units, and micro-actuators.
