The MTR-2523 is engineered for high-duty-cycle performance where weight-to-power ratios are critical. Its technical specifications reveal a motor built for high-torque delivery:
High Power Density: Operating at 48V, this 105g motor delivers a rated power of 157W. Its 20-pole configuration is specifically designed to provide high torque at moderate speeds.
Torque Characteristics: It features a rated torque of 0.3 Nm, with a significant peak torque capability of 0.96 Nm. For specialized high-load applications, a version with a 0.5 Nm rated torque is also available.
Dynamic Range: With a rated speed of 5000 RPM (peaking at 6200 RPM) and a torque constant of 0.089 Nm/Arms, the motor is ideal for direct-drive systems that require rapid acceleration without the backlash of a gearbox.
Engineering Integration & Thermal Management
As a frameless system, the MTR-2523-S000 requires the customer to provide the housing, shaft, and bearings. This shifts several technical requirements to the system integrator:
Precision Alignment: Maintaining stator-rotor concentricity is vital. The 20-pole radial flux design requires precise air-gap management to ensure uniform torque and prevent magnetic saturation.
Thermal Sinking: Without a dedicated frame, heat removal is achieved via conduction through the mounting structure. Given the 157W power rating, utilizing aluminum mounts with high thermal conductivity is essential to maintain the Class B insulation limits.
Electrical Reliability: The motor is built for harsh environments, featuring an insulation resistance of 100MΩ/500VDC and a dielectric strength of 1000VAC, ensuring stability in industrial or aerospace power grids.
Conclusion
The MTR-2523 provides the "performance ceiling" required for heavy-lift UAVs, industrial robotics, and high-precision rotary tables. While it requires a higher initial engineering investment for mechanical integration, the resulting system is lighter, more efficient, and more reliable than any other alternative.
