Specifications
All the products in our store are manufactured by us with great care. You knew that, but we get why you clicked the tooltip - and thanks.
The stator size of our motors is indicated as a combined number, where the first two digits refer to the stator width, and the last two digits refer to the stator height.
So a 4730 stator size refers to a motor with a stator width of 47 mm, and a stator height of 30 mm.
On large industry models with a stator diameter in exess of 100 mm (like our Jetstream Heavy Duty Series, these numbers are seperated by a dash, like 100-30 or 150-50.
The motor configuration gives you information about the number of stator arms/slots (N) and magnetic poles (P). So a 12N10P denomination refers to a motor with 12 arms and 10 poles.
This information includes the number of mounting holes, their respective thread size, and the bolt circle on which the holes are placed — shown as the number in brackets.
Example 1: "4x M4(30)"
This means that the motor features four M4 mounting holes, placed on a 30 mm bolt circle.
For extended compatibility with a wide range of models, some of our motors feature a combination of different mounting hole sizes and/or bolt circles. In this case, the information is shown as follows:
Example 2: "2x M4(30) + 2x M3(25)"
This means that the motor features two M4 mounting holes placed on a 30 mm bolt circle, and two M3 mounting holes placed on a 25 mm bolt circle.
Don’t worry if only two of the mounting holes, opposite to each other, line up with your mounting bracket or motor plate. Using only two screws is perfectly fine — but as with any metal thread, always use threadlocker.
This number refers to the legth of the motor body excluding the shaft, so from the mounting plate to the top of the rotor.
This number refers to the width (maximum extension from side to side) of the motor.
When checking the clearance in your frame, this is the number to compare it against.
