Mxus 45H v3 3K-Turbo 3000W Electric Motor (16x4) Rear

What you should know before buying the mxus v3 3k-turbo 3000w 45h electric motor?

The optimal selection of the Mxus 3K motor depends on the rim size as follows:
Up to 24" = faster winding 21x3 (3T)
26" = universal winding 16x4 (4T)
27.5/28/29" = slow winding 12x5 (5T)

The motor is recommended for all bikes designed for a sporty riding experience.

It offers the best price-performance ratio and the greatest potential for future drive upgrades.

The optimal controller should have 45A at 48 or 60V (We highly recommend SINUS controllers) to minimize motor heating at maximum power.

The 16x4 motor version is the most versatile winding, combining high maximum speed and high torque. We recommend this winding when converting a classic bike into its sporty electric version.

The motor has two interchangeable sets of Hall sensors. For daily use, only one set is connected. In case of Hall sensor failure, the second set can be used.

High-quality motor from Mxus. This is the latest version of the motor, known as "v3-Turbo".

Changes compared to the V2 version:

- Curved, thicker magnets
- Thicker power wires
- Thicker axle
- 2 sets of Hall sensors, KTY83 temperature sensor (for Sabvoton controller), and NTC10k (for sinus KT controllers)

Important tips for the mxus 3k turbo electric motor

The motor has 2 DIFFERENT temperature sensors. The first set of Halls has a KTY-83 sensor for Sabvoton controllers, and the second set of Hall sensors has an NTC10k sensor for sinus KT controllers. This allows the motor to be used with both types of controllers. To distinguish which of the white temperature sensor wires goes to which version, measure the resistance between the white wire and the black GND of the Hall sensors. If the measurement shows a resistance of ~1kΩ = KTY83, if ~10kΩ, it is NTC10k. The white temperature sensor wires are not assigned to specific sets of Hall sensors, so you can use one set of Hall sensors and a sensor from the second set.

Remember, this is a powerful and capable motor. Just like others, if it is used at the edge of its capabilities (55A or more), you should provide thermal protection for it.

For the v3 version, there is no need to double the phase wires; they are already sufficiently thick for maximum power. Installing a thermal switch is also made easier because you can use the 2 white wires from the temperature sensor, which are usually not used (the motor has 2 different sensors, but only one is used at a time). In the motor, disconnect the wire from the sensor and connect it to the 140 NO thermal switch.

What do the parameters 16x4 in the motor description mean?

Each motor can be described by two parameters: speed and torque. Both of these parameters are reflected in these mysterious 2 digits. They describe the internal construction of the motor. The first digit is the wire winding diameter, which directly affects the rotational speed, i.e., how many revolutions per minute the motor will reach for each 1V of power supply. The second number is the number of windings, indicating the torque that the motor possesses, i.e., the power it has during acceleration or uphill riding.
