M.T motor Germany M.T model M.T price

M.T motor is an AC motor that generates 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 mainly 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 by-products, etc. They feature simple structure, ease of manufacturing, low cost, reliable operation, durability, high operating efficiency, and suitable working characteristics.

M.T motor speed control

Motor speed control: Pole-changing speed control achieves speed regulation by changing the wiring method of the stator windings to alter the number of pole pairs in the stator of a squirrel-cage motor. Its characteristics are as follows: 1, it has stiff mechanical characteristics and good stability; 2, there is no slip loss, resulting in high efficiency; 3, the wiring is simple, control is convenient, and the cost is low; 4, it provides stepped speed control with large step differences, so smooth speed control cannot be achieved; 5, it can be used in combination with voltage-regulating speed control or electromagnetic slip clutches to achieve smooth speed control with higher efficiency. This method is suitable for production machinery that does not require stepless speed control, such as metal cutting machine tools, elevators, lifting equipment, fans, and water pumps. Variable frequency speed control changes the frequency of the power supply to the motor stator, thereby changing its synchronous speed. The main equipment in a variable frequency speed control system is the inverter that provides variable frequency power. Inverters can be divided into two categories: AC-DC-AC inverters and AC-AC inverters. In China, AC-DC-AC inverters are mostly used. Its characteristics are: 1, high efficiency with no additional losses during speed control; 2, wide range of applications, suitable for squirrel-cage asynchronous motors; 3, wide speed control range, stiff characteristics, and high precision; 4, complex technology, high cost, and difficult maintenance and repair. 5, this method is suitable for occasions requiring high precision and good speed control performance. Cascade speed control involves inserting an adjustable additional electromotive force into the rotor circuit of a wound-rotor motor to change the motor's slip, achieving speed control. Most of the slip power is absorbed by the inserted additional electromotive force, and then additional devices are used to return the absorbed slip power to the grid or convert the energy for utilization. Depending on the method of absorbing and utilizing slip power, cascade speed control can be divided into motor cascade speed control, mechanical cascade speed control, and thyristor cascade speed control. Thyristor cascade speed control is mostly adopted, with the following characteristics: 1, the slip loss during speed control can be fed back to the grid or production machinery, resulting in higher efficiency; 2, the device capacity is proportional to the speed control range, saving investment, and it is suitable for production machinery with a speed control range of 70%－90% of the rated speed; 3, in case of failure of the speed control device, it can switch to full-speed operation to avoid production stoppage; 4, the power factor of thyristor cascade speed control is relatively low, and harmonic influence is significant. 5, this method is suitable for use on fans, water pumps, steel rolling mills, mine hoists, and extruders.

M.T motor classification

A motor is a machine that converts mechanical energy into DC electrical energy. It is mainly used as a DC power source for DC motors, electrolysis, electroplating, electric smelting, charging, and excitation power for AC generators. Although power rectification components are used to convert AC to DC where DC power is needed, AC rectified power sources cannot completely replace DC generators in terms of certain performance aspects. A rotating device that converts DC electrical energy into mechanical energy. The motor stator provides the magnetic field, the DC power supply provides current to the rotor windings, and the commutator keeps the direction of the torque generated by the rotor current and magnetic field unchanged. Depending on whether a common brush-commutator configuration is installed, DC motors can be divided into two categories: brushed DC motors and brushless DC motors. Brushless DC motors are a new type of DC motor that has developed in recent years with the advancement of microprocessor technology, the application of new power electronic devices with high switching frequencies and low power consumption, the optimization of control methods, and the emergence of low-cost, high magnetic energy level permanent magnet materials. Brushless DC motors maintain the good speed control performance of traditional DC motors while offering advantages such as no sliding contact and commutation sparks, high reliability, long service life, and low noise. Therefore, they are widely used in aerospace, CNC machine tools, robots, electric vehicles, computer peripheral equipment, and household appliances. According to different power supply methods, brushless DC motors can be further divided into two categories: square-wave brushless DC motors, whose back EMF waveform and supply current waveform are both rectangular waves, also known as rectangular wave permanent magnet synchronous motors; and sine-wave brushless DC motors, whose back EMF waveform and supply current waveform are both sine waves.

M.T motor working principle

The DC disc brake of the motor is installed on the end cover at the non-shaft extension end of the motor. When the brake motor is connected to the power supply, the brake motor operates simultaneously. Due to electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, causing the brake disc to disengage from the armature end cover, and the brake motor starts to run. When the power is cut off, the electromagnet of the brake motor loses its magnetic attraction, and the spring pushes the armature to press against the brake disc. Under the action of frictional torque, the brake motor stops immediately. We also produce corresponding YDEJ two-speed (multi-speed, far-pole ratio) motors. The power supply for the brake motor is provided by the rectifier inside the motor junction box. For 3 kW and below, it is AC220V-DC99V; for 4 kW and above, it is AC380V-DC170V (special designs can also be made according to factory requirements, such as DC24V). The YEJ series electromagnetic brake motors can achieve rapid braking after power loss. The fast braking time for YEJ2-63-90 motors is less than 0.15 seconds, and for YEJ-100-160 motors is less than 0.20 seconds. Brake motors can achieve slow braking by changing the wiring in the junction box according to user requirements. This series of motors has low noise and reliable braking performance. Its working principle is: when the brake motor is energized, the brake motor obtains 198V DC power through 220V AC rectification. At this time, the armature is electromagnetically attracted, putting the brake disc in a rotatable state and allowing the brake motor to rotate freely. When the brake motor loses power, the electromagnet loses power, and the armature is immediately pushed by the spring to press the brake disc against the rear end cover of the motor, stopping rotation.
