This is a standard brushed motor from Etronix, designed for use in Tamiya kit cars, FTX and HPI ready to run cars and similar.

Please ensure you have a suitable ESC - motors are rated in turns, you need an ESC with an equal (or ideally lower) turn limit.  For example, a 15 Turn ESC will run a 15 or 19 turn motor but will not support a 13 turn.  A 550 size motor can usually simply replace a 540 size, the difference is a few millimetres of length.

The higher the number, the slower the motor and the longer the run time.

Common ESCs and their suitability for this range of motors are as folllows:

Tamiya TBLE02/TBLE04/TEU101BK-TEU106BK - These support the 27 and 35 motors.
Mtroniks Sport 20 / ECO 20 - These support the 21, 27 and 35 motors.
Etronix ET0102/ET0103 - These support the 15, 21, 27 and 35 motors.
Carson Dragster - This supports the 21, 27 and 35 motors.
HPI Maverick Quantum and Phantom - These support the 15, 21, 27 and 35 motors.
HPI Maverick Strada Series - These support the 21, 27 and 35 motors.
HPI Jumpshot - These support the 12, 15, 21, 27 and 35 motors.

Note that no standard ESCs support the 12 turn motor, this would require an ESC rated at 9 or 11 or unlimited turns, which are quite unusual.
