Product catalog summary

Overview: The document provides detailed specifications for the 16X401 slotless brushless motor, which is a 16 mm diameter, 2-pole motor designed for high efficiency and performance.

Specifications: The motor is available in four voltage variants: 18V, 24V, 36V, and 48V. Key performance metrics include a maximum continuous torque ranging from 14.0 to 15.7 mNm, a nominal output power between 63 to 71 W, and a maximum efficiency of up to 91.5%. The motor's speed varies with voltage, with no-load speeds between 56,700 to 61,220 rpm and nominal speeds from 54,146 to 58,450 rpm.

Thermal and Mechanical Data: The motor operates within an ambient temperature range of -40°C to 100°C, with a maximum winding temperature of 155°C. It features a mechanical time constant of 1.49 ms and can reach a maximum speed of 80,000 rpm. The motor is equipped with ball bearings preloaded to 2.5 N and can handle a maximum axial load of 2.5 N dynamically.

Electrical Characteristics: The motor has a torque constant ranging from 2.80 to 7.89 mNm/A and a speed constant between 1,211 to 3,409 rpm/V. Terminal resistance and inductance vary with voltage, affecting the motor's performance characteristics.

Connection Details: The motor includes three phases with specific color-coded wires for connection. Optional Hall sensors and NTC components are available for enhanced functionality, with detailed wiring instructions provided.

Miscellaneous: The motor has a rotor inertia of 0.533 g·cm², a typical noise level of 35 dB(A) at 50,000 rpm, and weighs 55 grams. It is designed with a 2-pole, 3-phase configuration.

Note: Specifications are subject to change without notice, and the document is valid as of July 2025.
