Micro Brushless DC Motors

Product catalog summary

General Overview: The document provides comprehensive technical specifications for various models of brushless DC motors manufactured by Telco Intercontinental Corporation. These motors are designed for high efficiency and performance, suitable for applications requiring precise control and reliability.

Specifications: Each motor model is detailed with specifications such as the number of phases, poles, operating temperature range, commutation type, bearing type, housing and magnet materials, direction of rotation, insulation class, dielectric strength, and insulation resistance. Key performance metrics include nominal voltage, phase resistance, output power, maximum efficiency, no-load speed, no-load current, stall torque, friction torque, back EMF constant, torque constant, slope of speed vs. torque curve, mechanical time constant, rotor inertia, maximum angular acceleration, sensor type, driver recommendation, weight, and motor body length.

Materials and Construction: The motors feature aluminum housing with a black anodized finish and sintered Nd-Fe-B magnets. They are electronically reversible and have a Class B insulation rating, capable of withstanding up to 500 VDC for one minute with a minimum insulation resistance of 100 Mohms at 500 VDC.

Performance Characteristics: The document outlines performance metrics such as output power, efficiency, speed, load current, operating torque, and maximum efficiency for each motor model. These metrics vary across models, reflecting their suitability for different applications.

Driver and Sensor Recommendations: Most models are sensorless, with some equipped with Hall sensors. Recommended drivers include models like TTDA5145 and DR33033, depending on the specific motor model.

Mechanical and Electrical Properties: The motors are designed to operate within a temperature range of -30°C to 85°C. They feature ball bearings for smooth operation and are available in various body lengths and weights, tailored to specific application needs.

Additional Features: Some models include additional specifications such as Hall-effect angles, shaft run-out, radial and axial play, maximum radial and axial loads, and maximum operating altitude. Electrical connections are detailed with lead color and function descriptions.

Applications and Recommendations: The motors are suitable for applications requiring high precision and efficiency, such as servo systems. Driver recommendations are provided for optimal performance, with the DR33033 being a common choice.
