Product catalog summary

Overview: This document provides technical specifications and operational guidelines for the 2019 edition of DC-Micromotors with precious metal commutation, specifically the Series 1219 ... G. The motors are designed for precision applications with a nominal power of 2 W and a torque of 0.72 mNm.

Specifications:

Nominal Voltage: Available in 4.5V, 6V, 12V, and 15V variants.
Terminal Resistance: Ranges from 10.7 Ω to 131 Ω depending on the model.
Efficiency: Maximum efficiency ranges from 70% to 74%.
No-load Speed: Between 15,300 min-¹ and 16,200 min-¹.
Stall Torque: Varies from 0.96 mNm to 1.19 mNm.
Torque Constant: Ranges from 2.76 mNm/A to 8.61 mNm/A.
Operating Temperature: Standard range is -30°C to +85°C, with an optional extension to +125°C.
Material: Housing is made of nickel-plated steel, and the magnet material is AlNiCo.

Performance Characteristics:

Rated Torque: From 0.62 mNm to 0.72 mNm for continuous operation.
Rated Speed: Between 2,770 min-¹ and 4,040 min-¹.
Thermal Resistance: Rth1/Rth2 is 17/48 K/W.
Thermal Time Constant: τw1/τw2 is 3.5/386 seconds.

Mechanical Features:

Shaft Bearings: Sintered bearings with specific load capacities.
Shaft Play: Radial play ≤ 0.03 mm and axial play ≤ 0.2 mm.
Mass: 11 grams.
Direction of Rotation: Clockwise when viewed from the front face.

Operational Guidelines:

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

Additional Options:

Extended temperature range and additional shaft end options are available.
Various product combinations with precision gearheads, encoders, and drive electronics are offered.

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

FAULHABERDC-Micromotors Precious Metal Commutation Rated values are calculated with nominal voltage and at a 22°C ambient temperature. 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.
