BLW50
Ritscher
Overview
The BLW50 is a premium, compact-frame Brushless DC (BLDC) motor engineered for applications requiring a balance of high power density, efficient operation, and reliable performance. Designed with advanced electromagnetic components and robust construction, this motor delivers smooth torque, excellent speed control, and long service life, making it an ideal drive solution for industrial automation, medical devices, robotics, and precision equipment where space and performance are critical.
Key Features & Advantages
High Power & Torque Density: Utilizing high-grade permanent magnets and optimized winding technology, the BLW50 delivers substantial continuous and peak torque relative to its compact 50mm-class frame size, enabling powerful performance in space-constrained designs.
Exceptional Efficiency & Thermal Performance: Engineered with low-loss magnetic materials and efficient thermal design, this motor operates at high electrical efficiency (>85%), minimizing energy waste and heat generation. This allows for higher continuous output and improved reliability.
Smooth & Precise Operation: Features low cogging torque design and precision-balanced components, resulting in exceptionally smooth rotation with minimal vibration—critical for applications requiring high positional accuracy or low acoustic noise, such as optical systems or laboratory automation.
Robust & Durable Construction: Built with a high-strength aluminum alloy or steel housing, high-temperature Class F or H insulation, and precision bearings. The motor is designed to withstand demanding industrial environments, including exposure to dust and moisture (available in IP54 or higher protection).
Wide Speed Range & Control Flexibility: Capable of operating across a broad speed spectrum, from low speeds with high torque to high rotational speeds. Fully compatible with standard BLDC motor controllers (ESCs), supporting speed, torque, or position control modes, and compatible with optional encoders for closed-loop applications.
Maintenance-Free & Long Lifespan: The brushless design eliminates brushes and commutators, the primary wear components in brushed motors, ensuring a long operational life with minimal maintenance requirements.
Standardized Mounting & Integration: Designed with industry-standard mounting interfaces and shaft configurations, ensuring easy integration into existing systems, compatibility with common couplings, and straightforward replacement.
Typical Specifications (Representative)
Model: BLW50
Motor Type: 3-Phase, Inner Rotor Brushless DC Motor (BLDC).
Frame Size: ~50mm (indicative diameter, to be confirmed via datasheet).
Rated Voltage: Common DC voltages: 12V, 24V, 36V, or 48V DC.
Rated Power: Typically in the range of 50W to 200W.
Rated Speed: Commonly available in 3000 RPM, 4500 RPM, or 6000 RPM variants (at rated voltage).
Rated Torque: Estimated continuous torque range: 0.1 Nm to 0.6 Nm.
Feedback Options: Standard Hall-effect sensors for commutation; optional incremental or absolute encoders.
Protection Class: Typically IP54 (splash-proof) as standard.
Primary Applications
Industrial Automation: Small robotic actuators, conveyor drives, valve controllers, CNC accessory drives.
Medical & Laboratory Equipment: Pump drives, analyzer mechanisms, adjustable positioning stages.
Precision Instruments: Optical scanner drives, laser positioning systems, coordinate measuring equipment.
Professional & Commercial Equipment: High-performance cooling fans, small agitators, automated dispensers.

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.
