Coreless Motors for quiet, jerk free model railway operation

Perhaps you know the situation: a locomotive on the layout runs restlessly, the motor hums audibly and at low speed it stutters along the track. With a modern coreless motor you can turn such vehicles into pleasantly quiet models that can be controlled very precisely and run very smoothly, especially at low speeds.

Compared with many conventional model motors, coreless motors offer a much smoother running behaviour. Even at low speed the shaft rotates evenly without noticeable cogging. The result is that your locomotives pull away softly, maintain more constant speeds and show no jerking during shunting, in station areas or on finely detailed parts of the layout.

All coreless motors in this category are designed for an operating voltage of 12 V DC. This makes them ideal for common model railway systems and many conversion projects on locomotives and other vehicles.

A range of different sizes and power levels is available, with single or double shaft. This allows you to equip both compact multiple units with limited space inside and larger locomotives with more available space. For every motor the technical data such as speed, current draw and torque are listed clearly so that you can compare the characteristics directly.

A conversion to a coreless motor is particularly worthwhile if you

• want to modernise older locomotives with rough or loud running behaviour,
• appreciate smooth, jerk free running at low speeds,
• already use sound decoders and want the motor to be barely audible in operation so that it does not overpower the sound,
• need more tractive effort and confident running for longer or heavier trains,
• want to increase the running quality and long term value of your models.

If you are unsure which motor will fit your vehicle, it is best to use the dimensions and performance data of the existing motor and the technical information in the product descriptions as a guide. In this way you can estimate which size and which speed range will suit your conversion project.

With a coreless motor from GATRA Modellbau Union you can turn your locomotives into reliable, smooth running workhorses that impress on the layout with quiet, even operation and realistic running behaviour.
