BL42708-01-CTL-01
Ritscher
Overview
The BL42708 is a premium, industrial-grade Brushless DC (BLDC) electric motor engineered for applications demanding high power density, precise control, and exceptional reliability. As part of a specialized series, this model combines advanced electromagnetic design with robust mechanical construction to deliver superior torque, efficiency, and dynamic response in a compact form factor. It is an ideal drive solution for automation, robotics, electric mobility, and high-performance industrial equipment.
Key Features & Advantages
High Power & Torque Density: Utilizing high-grade permanent magnets and optimized windings, the BL42708 delivers substantial continuous and peak torque output relative to its size, making it capable of driving demanding loads with high acceleration and dynamic performance.
Exceptional Efficiency & Thermal Performance: Engineered with low-loss magnetic materials and efficient thermal management, this motor operates at high efficiency (typically >90%), minimizing energy waste and heat generation. This allows for higher continuous power output and improved reliability in demanding duty cycles.
Precision Engineering for Smooth Operation: Features low cogging torque design and precision-balanced components, resulting in exceptionally smooth rotation, minimal vibration, and quiet operation—critical for applications requiring high positional accuracy or low acoustic noise.
Robust & Durable Construction: Built with a high-strength aluminum or steel housing, high-temperature Class H insulation, and precision bearings (such as Japanese or German brand bearings). The motor is designed to withstand harsh environments, including dust, moisture (available in IP65-rated versions), and continuous operation.
Versatile Control Integration: Compatible with standard BLDC motor controllers (ESCs) and supports various control modes—including speed, torque, and position control. Can be paired with optional high-resolution encoders (absolute or incremental) for closed-loop applications requiring precise feedback.
Wide Operating Speed Range: Capable of operating across a broad speed spectrum, from low speeds with high torque to high rotational speeds, providing flexibility for diverse application requirements.
Standardized Mounting & Interfacing: Designed with industry-standard mounting patterns (such as NEMA or IEC flanges) and shaft configurations, ensuring easy integration into existing systems and compatibility with common couplings and gearboxes.
Typical Specifications (Representative)
Model: BL42708
Motor Type: 3-Phase, Inner Rotor Brushless DC Motor (BLDC)
Frame Size: Likely corresponds to a compact, high-power design (e.g., 42mm or 70mm frame reference)
Rated Voltage: Common range: 24V, 48V, or 72V DC (specific voltage to be confirmed via datasheet)
Rated Power: Estimated range: 100W to 500W+
Rated Speed: Varies with voltage and load; typical range 3000 to 8000 RPM
Rated Torque: Estimated continuous torque range: 0.2 Nm to 1.5 Nm+
Peak Torque: Significantly higher than rated torque for acceleration and overload conditions
Feedback Options: Standard Hall sensor commutation; optional optical or magnetic encoder
Protection Class: Typically IP54 (splash-proof) or IP65 (dust-tight and protected against water jets)
Cooling: Natural convection (TENV) or forced air cooling (TEFC) depending on model
Primary Applications
Industrial Automation: Robotics (arm joints, grippers), CNC machinery, conveyor drives, automated guided vehicles (AGVs)
Electric Mobility: Light electric vehicles (e-bikes, scooters), drone propulsion, electric wheelchairs
Precision Equipment: Medical devices, laboratory automation, optical positioning systems
High-Performance Tools: Electric power tools, pumps, compressors, fans

Our company FAQ for you
(1) Q: What kind motors you can provide?
A:For now,we mainly provide Kitchen Hood Motor,DC Motor,Gear Motor,Fan Motor Refrigerator Motor,Hair Dryer Motor Blender Motor Mixer Motor,
Shade Pole Motor,Capacitor Motor,BLDC Motor PMDC Motor,Synchronous Motor,Stepping Motor etc.
(2) Q: Is it possible to visit your factory
A: Sure. But please kindly keep us posted a few days in advance. We need to check our
schedule to see if we are available then.
(3) Q: Can I get some samples
A: It depends. If only a few samples for personal use or replacement, I am afraid it will
be difficult for us to provide, because all of our motors are custom made and no stock
available if there is no further needs. If just sample testing before the official order and
our MOQ, price and other terms are acceptable, we'd love to provide samples.
(4) Q: Is there a MOQ for your motors?
A: Yes. The MOQ is between 1000~10,000pcs for different models after sample approval.
But it's also okay for us to accept smaller lots like a few dozens, hundreds or thousands
For the initial 3 orders after sample approval.For samples, there is no MOQ requirement. But the less the better (like no more than 5pcs) on condition that the quantity is enough in case any changes needed after initial testing.
