First, to get a firm understanding of what a coreless motor is, let’s first look at what a standard motor is. When a motor is said to be “iron cored”, then that’s a standard motor. This standard type of motor would have main parts such as iron-made rotor having wire coils around it. It would also have magnetic pole pieces surrounding it. Such motors are usually open framed and sometimes surrounded with a can.
But a coreless motor, on the other hand, is different because it has more than one coil of wires and these look more like a kind of open basket. With this type of motor, there’s a magnet in the center of the coils. There’s also a can in the outside of the motor which is specifically made to keep all of the parts of the motor together.
The advantage of this motor over others is this – the field which is magnetic where the armature rotates is far stronger, thereby helping to make it much more effective as a motor. But of course, it does have its disadvantages, like everything else in life.
Depending on the coreless motor you need, there are different models with different operation voltages. For example there is the TCL412 model with an operation voltage of 1.1 – 4.0V and D x M (mm) of 4 x 12. There’s also the TCL410 model with an operation voltage of 1.0 – 4.0V and D x M (mm) of 4 x 10.
Other types of this motor that you can find include the TCL610 model with operation voltage of 1.0 – 1.7V and D x M (mm) of 6 x 10, the TCL716 model with operation voltage of 1.1 – 1.7V and D x M (mm) of 7 x 16.
Apart from these, there are other coreless motor specs that might suit your need. Take your time when searching so that you find the one that will suit your needs. And yes, you can get and order for these on the Internet. Many of the good coreless motor manufacturers such as TecoElectric now sell these on the Internet from their websites.
