This is a high efficiency of inductive hall, permanent magnet brushless dc torque motor, the maximum rated power output can reach700 w., torque/speed5.4 NM / 1200 RPMOriginal, independent research and development work, do not plagiarize.The contour diameterThe 159.2 MM, flat, ultra-thin thickness31 mm, full metal jacket.Lever effect, because of the large outer rotor diameter significantly, compared with the same power wellies type motor, torque is bigger, a lower speed, can be used as power straight from gear so as to improve displacement efficiency, lower noise.This machine adopts the aluminum alloy as a support frame, with light weight, smooth speed regulation, large torque density, etc.The motor is structurally permanent magnet type synchronous motor, three-phase, adaptation to purchased brushless motor drive can use, due to its extremely logarithm, has the high score, so it is also applicable to synchronously driven by frequency conversion adjusting speed or position control, implementation is similar to the Angle of the stepper motor control, according to the three phase six control can reach the lowest resolution2.4An angular displacement, for accuracy is not high, do not need to add the occasion of the encoder is also be considered.And it is also a generator, and accept what is driving force (such as water, wind, hand, running machine, Stirling engine, etc.) when the output three-phase alternating current, three-phase rectifier bridge can be added into dc, recharge battery and other equipment, power supply.Because of this motor has simple structure, convenient disassembly and assembly, flexible installation fixed way, large hollow shaft design, the motor shaft and both end face can be used for a fixed load (or end) equipped with rotary encoder, compact structure, is all kinds of industry product development power source of choice.

This machine adopts a custom domestic large diameter bearing connection of stator and rotor, structure is simple, reliable, able to withstand radial, axial and upsetting force loads from all directions, the motor can run lasting.Because of bearing itself exists natural clearance, may lead to motor mild resonance under a certain speed, sound, usually after applying load can effectively restrain the phenomenon, is not a quality problem, the company shall not accept such after application.This motor grooveveryCombination of 45 slot 50, utilization rate is high, the winding magnetic potential polymerization degree is high, the electromagnetic torque is big, can maximize electrical comprehensive performance.Special note: this product without the detailed dynamic balancing correction, there may be vibration motor in high speed range, reduce the vibration value, as far as possible when shipment but cannot guarantee the specific data.
This motor before officially put into use, please in advance, for bearing to fully extend bearing life.The running-in method:The motorIn 500 ~ 600 RPM speed under no-load running 2 ~ 3 hours, and then increase to 1000 turn to run 2 ~ 3 hours, and so on.Because the motor no-load speed up to 1500 RPM, highest new motor using new bearing measured the speed have a slight fever, please pay attention to when high-speed running in bearing heating, such as after a long time in still overheating phenomenon, must strengthen the cooling, or reduce the speed to use.Such a problem does not belong to quality problem, don't accept such after application.
The form a complete set of motor drive can be directly control potentiometer (0 ~ 5 v analog voltage or PWM speed regulation) rotating speed racing minimum to 15 seconds, thanks to its use more slot multipolar structure and hall sensor components, ensure it can work normally under extremely low speed.Motor load is working, the winding coil (copper loss), core (iron loss), bearing (friction) will be fever, constitute the stator temperature rise after three heat polymerization, when installation, please send the stator base fit closely on the good performance of thermal conductivity of metal stents, if necessary can be coated on the surface of the joint thermal conductive silicone, to make full use of metal stents will export quantity of heat, reduce the temperature rise.The motor shell for the open architecture, good natural cooling condition, if conditions permit, auxiliary heat dissipation can be mounted to a cooling fan, motor torque and power can improve 40% ~ 100% again.

The above features is figure byMeasured after get related parameters calculated import RMxprt model simulation results, not to drive loss, bearing damping and friction, wind resistance and other factors into consideration, and the actual test value is likely to bias, are for reference only.Different batches of product parameters may be fine-tuning, no further notice.Wide working voltage range of brushless motor, voltage, the rated speed (long-term load working point) are also different.Speed is proportional to the voltage, torque and current is roughly proportional to, under the condition of natural cooling, rated maximum torque is less than 5.4 N * m, ratedThe biggestThe electric current shall not exceed 11. A, motor in low speed range (below 300 RPM) rotor air cooling effect is poorer, armature winding commutation frequency is low, lead to motor temperature increased, at this time should be appropriate to reduce motor current or to take active measures to cool.Above is voltage and rotating speed, the relationship between electric current and torque, in simple terms, the motor under a certain voltage, there will be one of the biggest appropriate sustainable operation torque, the torque is called stall torque (also called a rated torque), namely by light to load one of the lowest limit speed (rated speed), foreign output torque under the rotating speed is the stall torque, experience has shown that the lower limit rotational speed is usually no-load speed of 82% - 88%, most efficient motor produce less heat, but the small output torque, if want to increase the torque or speed, can be appropriately increasing voltage or current to achieve a goal, the motor temperature increase at the same time, as long as the motor temperature, bearing (winding) not to exceed 80 degrees, or to strengthen heat (such as a cooling fan) to control the motor temperature rise, the motor is relatively safe.So when doing motor selection, user should according to their own needs (speed torque) to select the appropriate power of motor, avoidThe motorOverload burning or a big horse power margin is too large the waste car.To sum up, this store has faithfully inform the user to use this product possible risks associated with the use of knowledge, knowledge prior to purchase.
