Product catalog summary

Overview: The document provides detailed specifications for the 22X452 series of slotless brushless motors, which are 22 mm in diameter and feature a 4-pole design. These motors are designed for high efficiency and performance, with a focus on compact size and power density.

Specifications:

Voltage Supply: Available in 18V, 24V, 36V, and 48V variants.
No-load Speed: Ranges from 22,100 to 23,353 rpm depending on the model.
No-load Current: Varies from 100 mA to 275 mA.
Max. Continuous Torque: Between 48.8 mNm and 51.8 mNm.
Max. Continuous Current: From 2.92 A to 7.76 A.
Nominal Speed and Torque: Nominal speeds range from 20,869 to 22,061 rpm, with nominal torques between 44.9 mNm and 47.8 mNm.
Nominal Output Power: Consistently at 104 W across models.
Efficiency: Maximum efficiency ranges from 90.0% to 90.9%.
Torque and Speed Constants: Torque constant ranges from 7.34 mNm/A to 20.15 mNm/A, while speed constant ranges from 474 rpm/V to 1,301 rpm/V.
Thermal and Mechanical Data: Operates in ambient temperatures from -40°C to 100°C, with a maximum winding temperature of 155°C. The mechanical time constant is 1.83 ms, and the maximum speed is 63,000 rpm.
Load Capacities: Maximum axial load is 4.2 N (dynamic) and 125 N (static), with a radial load capacity of 16 N at 5 mm from the flange.

Connection Details:

Phases: Three phases with specific color coding for connections.
Hall Sensor (Optional): Operates between 2.8 to 24 VDC with specific color-coded connections.
NTC (Optional): Two connections, both purple, for temperature sensing.

Additional Information: The motor weighs 120 g and has a rotor inertia of 5.8 g·cm². The typical noise level is 42 dB(A) at 25,000 rpm. Specifications are subject to change without notice.
