Product Description

Motor diameter: 36.5 MM Motor length: 61 MM Motor shaft diameter: 5 MM (the end is 3.9MM orthodontic thread) Output shaft length: 35.5 MM Lead length: about 90 MM (8 P) Weight: 232 grams (Among them, three thick wires are three-phase main wires of the motor, and five thin wires are Hall five wires)

(The brown line in the Hall's five lines is positive, the blue line is negative, and the other three lines are output lines)

Brand new original Japanese (Sinano) DC brushless motor, inner rotor, no drive board, with Hall, three-phase eight-wire DC brushless motor, one is 30 PCS, complete packaging, very exquisite workmanship, beautiful appearance, and It is a batch of high-quality DC brushless motors. Although this motor is not big, but its power is not small, the outer diameter is 36.5 MM, which is much smaller than the previous batch of Nidecco DC brushless motors (outer diameter 41.8MM), but it is heavy in weight and has the same weight The Nidko motor is the same weight, and the power is about the same.

The rated power of this batch of motors is DC105V, but after power-on test machine, it is suitable for a wide range of voltages. The working state is very good at DC36V, DC48V, DC60V, mute, large torque, although the voltage is reduced a little, the power is weakened However, the torque is quite strong, and it is quieter. It should be less prone to heat and more suitable for long hours of work. In fact, its torque is very good when it is DC24V. However, it should be noted that the line sequence of the Hall output line should be correct. If the line sequence of the Hall is not connected correctly, either the motor will not rotate or the motor will rotate much faster, the current is large but the torque is very small. Try two out of Hall's three output lines.

The surface of the rotor is painted black, and the surface is scraped off, and the composition of rare earth can be clearly seen. Although it is not a high-strength magnet of neodymium-iron-boron, it is very strong and is a medium-strong magnet.

The normal service life of the brushless motor is very long. The motor uses high-quality NMB ball bearings, which is more stable and more secure. Its lead end is an 8 P terminal, which can be cut directly if it is not used. The three thick wires (red wire, black wire, and white wire) are the three main wires of the motor:

The five thin wires are Hall's five wires. Among them, the colored wire is connected to the positive pole, the blue wire is connected to the negative pole, and the other three wires are the signal output lines. Note that the positive and negative poles cannot be connected wrong. The color of the Shinano motor wire is relatively light , Please pay attention to distinguish the color of the line carefully.

The universal drive of the electric vehicle can perfectly drive this motor (you can only connect 3 wires or 8 wires), you can also adjust the speed, you can also reverse the direction, if you only connect 3 wires, it can also drive it at DC12V, But if you want to connect 8 wires, the minimum voltage is DC24V to drive this motor, it is estimated that it is the relationship of Hall. However, the torque when DC12V is used is too small, in fact, it does not make much sense.

The rated voltage of this motor is DC105V, and the speed is estimated to be more than 10,000 rpm. We have no suitable driver to test it. We can only test its different speed below DC60V. The measured parameters are as follows: Voltage: DC24V Speed: 2800 rpm Voltage: DC30V Speed: 3500 rpm Voltage: DC36V Speed: 4300 rpm Voltage: DC48V Speed: 5800 rpm Voltage: DC60V Speed: 7100 rpm
