Installation and operation as long as the operation and installation of the machine, there is a certain risk, then install the operating gearmotor what to pay attention to? Before installation, you must first check the power-operated, and the determination can be installed, before you can carry out the following steps.

During the installation, you should protect the gear motor, so that he received from the impact of the shaft when the gear unit mounting structure, a shaft of the gear unit does not allow direct knock or press fit. Wire arrangement requires straighten, do not bend, it will affect the internal problems and poor motor point.

Do not force the rotation from the output shaft reducer, otherwise it will cause gear damage. When the shaft of the gear unit with an adhesive fixed transmission structure, can not tack reducer bearings.

Brush motors and brushless motors difference:

1, brush motor

It uses a brushless motor power supply as the two contacts by the governor and the controller is controlled by the second reduction gear and clutch to achieve the electric bike 0-20 km / h stepless. Currently used in high-speed motor that has a brush of high gold content, strong reduction gear motor strength, wear resistance, reasonable design, it is a lower failure rates; and less maintenance and replacement gears and motors cost effective to reduce the electric bike maintenance costs; and a brush motor can be achieved easily by human riding clutch and flywheel. Brush Motor is the use of the brush mechanically commutated!

2, brushless motor

Its speed control system cost than brush motor speed control system for a high-speed controller in use prone to failure. When equipped with a brushless motor bike traveling speed must be to 35 km / hour, in order to play its best efficiency, but we know that as a non-motor vehicles electric bicycles to manage, it must speed of 20 km / h or less, it is brushless motor is electric bicycles chosen to reduce the work efficiency, it is desirable not strong. It is now used in the main point is noise. Brushless motor that uses electronic line-commutated! Polarity detecting element detects!

Here to talk about several aspects of brush motors and brushless motors difference:

1, the scope:

Brushless motor device can be used: the dairy industry, the brewing industry, meat processing industry, soybean processing industry, beverage processing industry, pastry industry, pharmaceutical industry, precision electronics factory, and some more demanding clean room and so on, like Dior electrical capacity brushless motor (DIHOUR) dry hands, use the factory more.

Brushless motor: can only be applied to all kinds of toilets and other requirements are not too high for the region, but as clean room and workshop explosion can not be used!

2, life:

Brushless motor: can work for about 20,000 hours, regular life 7--10 years.

Brushless motor: it can work for about 5000 hours, regular life 2--3 years.

3, using the results:

Brushless motor: to 90-95m / s speed operation, the actual results can be achieved time 5-7s of dry hands.

Brushless motor: time running speed and dry hands is much lower than the brushless motor.

4, energy aspects:

In contrast, the power consumption of the brushless motor is brushless 1/3.

5, future maintenance

After the brushless motor wear, not only to replace the carbon brushes, also changing accessories and other electrical switch gear surrounding the cost much higher. Most importantly, the overall functionality will be affected.

6, noise and life

Noise emitted than brushless motor brushless motor much higher, and with the future of the carbon brush wear, brush motor noise will become increasingly large, and the brushless motor is not affected.

Three-phase asynchronous brake motors are totally enclosed fan-cooled three-phase squirrel cage induction motor with additional DC disc brake, brake motors with brake quickly, simple structure, high reliability, versatility, etc., brake motors are widely used species require fast stopping and precise positioning of equipment and gear, for example, packaging machinery, woodworking machinery, chemical machinery, textile machinery, construction machinery and other industries.

Three-phase asynchronous system

DC disc brake moving motor mounted on the motor non-drive end cap. Access to power when WEG brake motors, brake motors also work. Because electromagnetic suction effect, attracting electromagnet armature and compression springs, brake disc on the armature cover disengaged, the brake motor starts running. When the power is turned off, the brake motor solenoid lose magnetic force, armature spring pushes the brake discs pressed at the friction torque is applied, the brake motor stops immediately.

Electromagnetic brake three-phase asynchronous motors, also known as loss of power brake motors, brake asynchronous motor is totally enclosed, fan-cooled, squirrel cage, additional DC electromagnet brake three-phase asynchronous motors, brake motors have a high-precision positioning requirements, brake fast, accurate, safe and reliable brake system used interchangeably, the structure should be simple, easy maintenance and replacement and other characteristics.

Abstract: The start of the high frequency DC what impact, starting frequency DC motor is not too high, this is because the DC motor just starting speed is zero, therefore, pay special attention to during the operation.

DC motor starting frequency is not too high, this is because the DC motor just starting speed is zero, the starting process, in addition to overcoming the electromagnetic torque load resistance torque, but also to overcome the inertia of the rotating part of the mask, so the starter motor The burden is heavier than continuous operation.

If the initiating pulse frequency is too high, then the rotor speed to keep up with the speed of rotation of the stator magnetic field, so the first step completion position far behind in the equilibrium position, after each step increase in rotor speed is not much, but still stator field pulse frequency proportional to the rotational speed forward, so the distance between the rotor and the equilibrium position more and more, the final result of the rotor position falls outside the stable area and move a step out or oscillation, thus the motor can not be played

Move.

A variety of DC motor starting frequency varies, focusing miniature stepper motors and stepper motor drive shaft industrial products Solutions Expert letter electromechanical engineers need to follow the instructions recommended that data to determine the starting frequency of the motor, many high motor starting frequency using a dual voltage Operation starts from the moment the high voltage and low voltage changes, and step away from the smaller and more suitable for high frequency start, the greater the power the more suitable for high-frequency operation.

In order to properly start, starting frequency is not too high, when the motor starts and then gradually increase the frequency.
