Product Description Product DescriptionProduct Details of DC Motor1. Basic Parameters Rated Voltage:Common specifications: 1.5V, 3V, 6V, 12V, 24V, 48V, etc. (Low-voltage for small motors, 24V+ for industrial applications).Example: A toy motor may require 3V, while an industrial servo motor uses 48V. Rated Power:Range: From milliwatts (e.g., micro fans) to tens of kilowatts (e.g., electric vehicle drives).Unit: Watts (W) or Horsepower (HP, 1HP ≈ 746W). Rated Speed:Typical range: Several hundred RPM to tens of thousands RPM (e.g., high-speed spindle motors).Example: Common DC motors run at 1,000-3,000 RPM, while drone motors can exceed 10,000 RPM. Rated Current:Calculated by: Current (A) = Power (W) ÷ Voltage (V).Note: Starting current is typically 2-5 times the rated current. 2. Mechanical Parameters Torque:Rated Torque: Output torque under rated load (Unit: N·m or kg·cm).Starting Torque: Maximum torque at startup, usually higher than rated torque.Application: High-torque motors suit heavy-load scenarios like hoists. Shaft Diameter & Length:Common shaft diameters: 2mm (micro motors) to 50mm (industrial motors).Example: A micro motor might have a 3mm diameter shaft, 8mm long. Mounting Dimensions:Includes motor diameter, length, and base hole spacing for equipment installation. 3. Electrical Characteristics Efficiency:Typically 50%-90%, with permanent magnet motors exceeding 85%. Speed Regulation Range:Achieved via PWM (Pulse Width Modulation) or voltage adjustment, often 10:1 (e.g., 100-1,000 RPM). Insulation Class:Common classes: B (130°C), F (155°C), H (180°C). High-temperature environments require higher ratings. 4. Structure & Materials Types:Permanent Magnet DC Motors: Use permanent magnets (e.g., neodymium) for compact size and high efficiency.Brushed DC Motors: Feature carbon brushes for commutation, cost-effective but with limited lifespan.Brushless DC Motors (BLDC): Electronically commutated, offering longer life and higher speeds. Protection Class (IP Rating):Examples: IP44 (dust & splash-proof), IP65 (dust-tight & water jet-resistant). Outdoor use requires higher ratings. 5. Performance Curves Speed-Torque Curve:Describes speed changes under varying loads (permanent magnet motors typically show linear decline). Efficiency Curve:Shows efficiency across different load rates, peaking at 75%-100% load. 6. ApplicationsConsumer Electronics: Toys, toothbrushes, fans, shavers.Industrial Equipment: Conveyors, mixers, hoists, machine tool spindles.Transportation: Electric vehicles, wheelchairs, power tools.Automation: Robotic joints, servo systems, precision positioning devices.7. Complementary Components Drives:Brushed motors: Simple speed controllers or PWM modules.Brushless motors: Require dedicated ESC (Electronic Speed Controllers). Gearboxes:Reduce speed and increase torque (e.g., planetary or worm gear types). 8. Selection GuideChoose power and torque with 20%-30% margin for load fluctuations.High-temperature or wet environments demand higher IP and insulation ratings.Brushless motors are ideal for frequent starts/stops or precise speed control.Sample Product SpecificationsParameterMicro DC Motor (Toy)Industrial Servo Motor (Robot)Rated Voltage3V48VRated Power5W500WRated Speed3,000 RPM3,000 RPMRated Torque0.016 N·m1.6 N·mMotor TypePermanent MagnetBrushless Permanent MagnetProtection ClassIP20IP65Efficiency60%90% Product ParametersAfter Sales ServiceApplication of PM motor in the transformation of a ball milling machie in a certain factoryPM motor TYP280S-75kW replace the original motor Y280S-4-75kW.According to the comparison of on-site operation results, the energy-saving rate is 8%, the operation is stable, and the customer feedback is good.Packaging & ShippingFAQ1.Are you a factory?Yes,we have our own factory for manufacturing and we have the long history in this field as the China top brand.2.Can you provide free sample?Yes, we can provide samples in our stock for free, customer just need to bear the shipping fee.3.
