Overview


This series motor adopts modular design. It consists of four parts: torque motor, eddy current regulator, electromagnetic brake and fan, which can be flexibly configured to
meet different customer demands. With introduction of a new special brake, it can cater for outdoor and high-altitude operations. The product has reached the international
advanced level with the patent for utility model. It is mainly used as a trolley speed-change gear for tower crane as well as other mechanical equipments requiring for
constant power and stepless speed regulation.

FeaturesConstant tension and linear speed, stepless speed regulation, frequent starting;
Special eddy current regulator for the motor realizes smooth startup or stop;
New special brake (national utility model ZL201120188173.2, ZL2011201881643). This ensures fast braking and accurate positioning with higher safety and reliability
Besides, manual release is possible;
The rotor is made of copper alloy with better mechanical properties and mechanical bearing capacity in the domestic industry;
Spindle is hot forged by alloy structural steel,with good overall mechanical perlormancc;
A thermal protection component is buried into the in stator winding, making motor more safer and reliable;
Compact structure, small volume, lightweight as well as high reliability, so itfeatures easy maintenance and repair.

Q:How can I change the alternating current welding machine into a DC welder?
At the output end of AC welding machine ~ ~ two terminals, one rated welding output voltage is greater than 2 times the no-load voltage, rated output welding current is greater than 2 times the output current of the rectifier.
Q:In the main circuit of AC motor, fuse can be used as short circuit protection, can it play the role of overload protection at the same time, why?
Therefore, the overload protection of the motor requires the use of a thermal relay that can accumulate heat effects. When the accumulated heat reaches a certain degree, the protection is started, and the motor is not allowed to continue heating up.
Q:The difference between induction motor and induction motor
In fact, the same is true, asynchronous AC motor is the wire package after power generation magnetic field, and then the rotor will have a magnetic field, called induction magnetic field, their asynchrony, so called asynchronous AC motor
Q:What are the classifications of AC motors?
According to the different rotor structure, three-phase asynchronous motor can be divided into two major categories, squirrel cage and winding. Among them, squirrel cage is the most widely used.
Q:Which good reputation is synchronous synchronous motor?
You can see Wuxi city base metal products factory is a 50KTYZ permanent magnet synchronous motor, permanent magnet synchronous motor 60KTYZ, 65KTYZ permanent magnet synchronous motor, permanent magnet synchronous motor 80KTYZ, stepper motor products such as professional production and processing company, products are widely used in various types of household electrical appliances, office automation, automatic control etc.. Wuxi city base metal products factory from ultra early start to now and in the future, we are committed to providing high-quality products and services for customers from incoming, manufacturing, shipping and other processes in strict control of product quality, the production of motor advanced manufacturing technology as the premise, with modern production and testing equipment for the protection. The pursuit of zero product defect rate of PPM, is committed to providing customers to create large value add motor pursuit, to achieve the terminal customer satisfaction as the core; add motor is building motor manufacturing enterprises and make unremitting efforts.
Q:The direction of alternating current keeps changing. How about the direction of AC motor?
There are many ways to generate rotating magnetic field, such as three-phase winding method, single-phase phase-shifting method, short-circuit loop method, pulse commutation method, and so on.
Q:Can AC motors be controlled by frequency converter?
Only frequency conversion motor can use frequency converter to speed up, ordinary motor can not use frequency converter speed regulation.But it is possible to start the AC motor by using frequency converter.
Q:What are the advantages of a DC motor and an AC motor?
The DC motor consists of two parts, stator and rotor, in which there is a certain air gap. The main feature of the structure is that it has an armature with a commutator. The stator of a direct current motor consists of a machine base, a main magnetic pole, a reversing magnetic pole, a front and back end cover, and a brush rack. The main magnetic pole is the main component of the air gap magnetic field of the DC motor. It is composed of a permanent magnet or a laminated core with a DC exciting winding. The rotor of the DC motor armature, the commutator (also called commutator) and shaft components. The armature is composed of two parts: armature core and armature winding. The armature core is made up of silicon steel sheets, and the slots are evenly distributed at its outer circle, and the armature windings are embedded in these slots. A commutator is a mechanical rectifier. The sheet is made of a metal clip or plastic to form a whole after it is folded into a cylindrical shape. Each commutator piece is insulated from each other. The quality of commutator has a great influence on the operation reliability.
Q:Relation of voltage, speed, voltage and torque of single phase AC motor
The voltage and torque is constant (c= C T= square poles P * * * the number of turns of the stator voltage of U / L) * f (frequency rotor resistance + leakage resistance)The voltage is low rotational speed torque, output torque of the motor load torque is not greater than the operation of what the problem is, if the motor in full load and overload operation will reduce the service life of the motor, the motor blocking words soon consumed.If the economy allows, you can use single-phase frequency conversion speed control, variable frequency speed regulation, rated frequency speed regulation is constant torque output.
Q:Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?
AC motor: wind, make the sound small, more durable, hot and cold big difference, large volume, stable current to prevent overvoltage protection AC fever dead machine, most hair dryer is now all communication, have built-in motor protection diode
