Magnetic Powder Dynamometer High Precision Torque Power Tester for Motor Factory Direct SupplyUS$ 5000MOQ: 1 Set
Our micro motor dynamometer is a high-precision, compact test system exclusively designed for small motors, micro motors, precision motors, toy motors, and medical miniature motors. It accurately measures torque, speed, output power, input current, voltage, efficiency, and temperature rise in real time, covering ultra-low torque ranges from 0.001 mN·m to 500 mN·m and speeds up to 60,000 rpm. Ideal for R&D, quality control, mass production testing, and certification of tiny motors used in medical devices, toys, consumer electronics, and precision instruments.
Key Features
Ultra-High Precision: Torque accuracy ±0.1% FS, speed accuracy ±0.01% FS; resolves as low as 0.0004 mN·m for micro-torque testing.
Wide Compatibility: Works with DC brushed/brushless, shaded-pole, coreless, and tiny BLDC motors; supports toy motors (1.5V–12V), medical small motors, and precision micro drives.
Stable Hysteresis Loading: Adopts hysteresis brake technology—no speed required to generate torque; enables full testing from free run to locked rotor (stall) with smooth, shock-free load control.
All-in-One Test Parameters: Automatically measures and records：
Torque (mN·m / g·cm)
Speed (RPM)
Output Power (W)
Input Voltage / Current
Efficiency (%)
Temperature Rise (°C)
Cogging torque & Back EMF
Automatic Testing & Reporting: Digital PID control for fast, stable load setting (locks in 2–3 seconds); one-click generation of Excel/PDF reports with characteristic curves (M=f(U,I,n,P,η)).
Compact & User-Friendly: Small footprint for lab use; intuitive software with multi-language support (EN/CN); minimal training required for operation.
Durable & Low Maintenance: Rugged mechanical structure with low residual torque and low inertia; designed for 24/7 continuous testing in mass production environments.
Applications
Medical Devices: Insulin pumps, surgical tools, hearing aids, and miniature actuators.
Toys & Consumer Electronics: RC cars, drones, smart toys, and small home appliances.
Precision Instruments: Optical equipment, robotics, and micro actuators.
Automotive & Aerospace: Tiny motors for sensors and control systems.
Education & R&D: University labs and motor manufacturer R&D centers.
Packing & Delivery
Packing: Standard export wooden case
Delivery: 7–15 days after order confirmation
Warranty: 12 months warranty with lifetime technical support
