1506 ... SR

Product catalog summary

Overview: This document provides technical specifications and operational guidelines for the 2019 edition of Flat DC-Micromotors with precious metal commutation, specifically the Series 1506 ... SR. These micromotors are designed for precision applications requiring compact size and efficient performance.

Specifications:

Nominal Voltage: Available in 3V, 6V, and 12V variants.
Terminal Resistance: Ranges from 13.5 Ω to 155 Ω depending on the model.
Efficiency: Maximum efficiency ranges from 62% to 67%.
No-load Speed: Varies from 11,100 min-¹ to 12,800 min-¹.
Stall Torque: Between 0.49 mNm and 0.64 mNm.
Torque Constant: Ranges from 2.46 mNm/A to 8.63 mNm/A.
Operating Temperature Range: -25°C to +80°C for the motor, with a maximum permissible winding temperature of +85°C.
Mass: 4.3 g.
Material: Housing made of plastic, with NdFeB magnet material.

Performance Characteristics:

Rated Torque: 0.37 mNm to 0.45 mNm for continuous operation.
Rated Speed: 2,500 min-¹ for all models.
Thermal Resistance: Rth1/Rth2 values are 25/35 K/W.
Thermal Time Constant: τw1/τw2 values are 4.5/48.4 seconds.

Mechanical Features:

Shaft Bearings: Sintered bearings with specific radial and axial load capacities.
Shaft Play: Radial ≤ 0.03 mm, Axial ≤ 0.2 mm.
Direction of Rotation: Clockwise when viewed from the front face.

Operational Guidelines:

The document includes a diagram indicating recommended speed in relation to available torque at an ambient temperature of 22°C.
Operational points above the nominal voltage curve require higher voltage, while those below require less.

Options and Accessories:

Motors are available with single or twin leads, and additional accessories such as precision gearheads, encoders, and drive electronics are available.

Note: Specifications are subject to change without notice, and further technical data and lifetime performance details can be found in the "Technical Information" section.

The Rh2 value has been reduced by 0%. Note: The diagram indicates the recommended speed in relation to the available torque at the output shaft for a given ambient temperature of 22°C. The diagram shows the motor in a completely insulated as well as thermally coupled condition (Rth2 50% reduced). The nominal voltage (Un) curve shows the operating point at nominal voltage in the insulated and thermally coupled condition. Any points of operation above the curve at nominal voltage will require a higher operating voltage. Any points below the nominal voltage curve will require less voltage.
