ATEK motor Germany ATEK model ATEK price

ATEK motors are AC motors that generate electromagnetic torque through the interaction between the rotating magnetic field in the air gap and the induced current in the rotor windings, thereby converting electrical energy into mechanical energy. Three-phase asynchronous motors are primarily used as motors to drive various production machinery, such as fans, pumps, compressors, machine tools, light industrial and mining machinery, threshers and crushers in agricultural production, and processing machinery for agricultural products, etc. They feature a simple structure, ease of manufacturing, low cost, reliable operation, durability, high operating efficiency, and suitable operating characteristics.

ATEK motor structure

A single-phase motor is an electric motor that operates on a single-phase AC power supply. A single-phase asynchronous motor consists of a stator, rotor, bearings, housing, end caps, and other components. The stator comprises a frame and a laminated core with windings. The core is made by stacking slotted silicon steel sheets. Two sets of main windings (also known as running windings) and auxiliary windings (also known as starting windings or secondary windings), spatially separated by 90° electrical degrees, are embedded in the slots. The main winding is connected to the AC power supply, while the auxiliary winding is connected in series with a centrifugal switch S or starting capacitor, running capacitor, etc., before being connected to the power supply. The rotor is a squirrel-cage cast aluminum rotor, formed by casting aluminum into the slots of the laminated core and simultaneously casting end rings to short-circuit the rotor bars, creating a squirrel-cage configuration. Single-phase asynchronous motors are further classified into single-phase resistance-start asynchronous motors, single-phase capacitor-start asynchronous motors, single-phase capacitor-run asynchronous motors, and single-phase dual-value capacitor asynchronous motors.

ATEK motor common issues

Can the motor be connected to a 50Hz power supply? During motor design, the silicon steel sheets are generally operated in the saturation region of the magnetization curve. When the supply voltage is constant, reducing the frequency increases the magnetic flux, which increases the excitation current, leading to an increase in motor current and copper losses. This ultimately causes the motor temperature rise to increase, and in severe cases, may burn out the motor due to coil overheating. Seven. What are the causes of phase loss in motors? Power supply side: (1) Poor contact at the switch; (2) Broken transformer or line wires; (3) Blown fuse. Motor side: (1) Loose screws in the motor junction box causing poor contact; (2) Poor internal wiring soldering; (3) Broken motor windings. Eight. What are the causes of abnormal vibration and noise in motors? Mechanical aspects: (1) Poor bearing lubrication, bearing wear; (2) Excessive bearing housing clearance. (3) Loose fastening screws; (4) Debris inside the motor. Electromagnetic aspects: (1) Motor overload operation; (2) Unbalanced three-phase current; (3) Phase loss; (4) Short circuit faults in stator or rotor windings; (5) Open welds in the squirrel-cage rotor causing broken bars. Nine. What are the causes of motor bearing overheating? Motor itself: (1) Excessively tight fit between inner and outer bearing rings; (2) Issues with geometric tolerances of components, such as poor coaxiality of the frame, end caps, shaft, etc.; (3) Improper bearing selection; (4) Poor bearing lubrication or incomplete cleaning, with debris in the grease; (5) Shaft current. Usage aspects: (1) Improper unit installation, such as non-compliant coaxiality between the motor shaft and the driven equipment shaft; (2) Over-tightened belt pulley; (3) Poor bearing maintenance, insufficient grease, or expired/dried-out grease. Ten. What are the causes of low motor insulation resistance? (1) Damp windings or water ingress; (2) Accumulation of dust or oil on windings; (3) Insulation aging; (4) Damage to motor lead wires or terminal board insulation.

ATEK motor classification

The basic components of a motor include the stator, rotor, brushes, and commutator. The interaction between the stator and rotor magnetic fields drives the motor rotation. Types of brushed DC motors are classified based on how the magnetic field is generated in the stator or housing. Depending on the type of brushed DC motor, the stator magnetic field can be generated by permanent magnets or windings in the stator. In the latter case, the stator windings and rotor windings can be connected in parallel, series, or compound configurations. These three types of brushed DC motors are respectively called shunt-wound motors, series-wound motors, and compound-wound motors.
