BL65
Ritscher
Overview
The BL65 Series is a high-performance, high-torque Brushless DC (BLDC) motor engineered specifically for demanding power transmission and drivetrain applications. Designed to serve as the primary drive or auxiliary power unit within complex transmission systems, this motor delivers robust, efficient, and controllable rotational force for industrial machinery, automotive systems, and specialized propulsion units where reliability and precise torque delivery are critical.
Key Features & Advantages
High Torque Density & Power Output: Engineered with high-grade permanent magnets and an optimized electromagnetic design to deliver exceptional continuous and peak torque within a compact 65mm frame. This enables direct driving of gears, shafts, or couplings in transmission systems without requiring excessive gearing.
Precise Speed & Torque Control: When paired with a compatible servo drive or controller, it offers excellent speed regulation and torque control. This allows for smooth engagement, synchronized motion with other drivetrain components, and adaptive power delivery based on load demands.
Robust Construction for Harsh Environments: Built with a heavy-duty housing (typically aluminum or steel), high-temperature insulation (Class H), and IP65-rated sealing as standard. Designed to withstand vibration, shock, dust, moisture, and temperature fluctuations common in industrial and mobile transmission applications.
High Efficiency & Thermal Management: Operates at high electrical efficiency (>90%), minimizing energy loss and heat generation. Integrated cooling fins or provisions for forced-air/ liquid cooling allow for sustained high-power output and improved thermal stability in continuous duty cycles.
Low Maintenance & High Reliability: The brushless design eliminates brushes and commutators—the primary wear components in traditional motors—resulting in dramatically extended service life, reduced downtime, and minimal maintenance requirements.
Integrated Feedback for Closed-Loop Operation: Standard configuration includes high-resolution encoders (absolute or incremental) or resolvers, providing precise rotor position and speed feedback for accurate closed-loop control within the transmission system.
High Overload Capacity: Capable of delivering 150-200% of rated torque for short durations, providing the necessary reserve power to handle startup inertia, shock loads, or transient overloads in the drivetrain.
Typical Specifications
Motor Type: 3-Phase, Inner Rotor Brushless DC Motor (BLDC) / Permanent Magnet Synchronous Motor (PMSM).
Frame Size: 65mm square flange (or as per BL65 designation).
Rated Voltage: Common ranges: 48V DC, 72V DC, 96V DC, or higher for industrial systems.
Power Range: Typically from 0.5 kW to 3 kW.
Rated Speed: Commonly 2000 RPM, 3000 RPM, or 4500 RPM, with a wide constant torque range.
Rated Torque: High, with a typical range from 2 Nm to 10 Nm+.
Feedback Device: Multi-turn absolute encoder standard.
Protection Class: IP65 (dust-tight and protected against water jets).
Cooling Method: Natural convection (IC410) or forced cooling (IC416).
Primary Applications in Transmission Equipment
Industrial Machinery: Main or auxiliary drives for conveyors, mixers, extruders, printing presses, and textile machinery.
Automotive & Mobile Hydraulics: Electric power steering (EPS) pumps, transmission oil pumps, cooling fan drives, hybrid/electric vehicle auxiliary drives.
Agricultural & Construction Equipment: Drives for implement adjustments, fan drives, pump drives in tractors and heavy machinery.
Specialized Drivetrains: Electric axle drives, test bench dynamometers, winch systems, and robotic joint drives.
Why Choose the BL65 Motor for Transmission Equipment?
For system integrators designing modern, efficient, and intelligent drivetrains, the BL65 Series provides a superior alternative to traditional AC induction or hydraulic drives. Its combination of high torque density, precise controllability, and rugged reliability enables the design of more compact, responsive, and energy-efficient transmission systems. By delivering clean, programmable power directly where it's needed, it enhances overall system performance, reduces maintenance costs, and supports the trend toward electrification and automation.
