CT INGRANAGGI motor, German CT INGRANAGGI model, CT INGRANAGGI price

CT INGRANAGGI motor is a single-phase AC commutator motor, suitable for single-phase power supply applications requiring speed regulation and reversal of rotation direction. The stator winding is powered by a single-phase source, and the rotor is an armature winding with a commutator short-circuited via brushes. The brushes can be moved to any position relative to the stator winding as needed. By shifting this position, the rotor's direction of rotation, mechanical characteristics, and operating speed can be changed. When the brushes are displaced counterclockwise from the geometric neutral axis, the rotor rotates clockwise; when the brushes are displaced clockwise from the geometric neutral axis, the rotor rotates counterclockwise.

CT INGRANAGGI motor applications

Compared with traditional reactive motors, the hybrid induction motor has permanent magnets added to the rotor structure to provide the operating point for soft magnetic materials, while the stator excitation only needs to provide a changing magnetic field without supplying the energy consumption for the magnetic material's operating point. Therefore, this motor offers high efficiency, low current, and low heat generation. Due to the presence of permanent magnets, the motor has a strong back EMF and good self-damping, resulting in smooth operation, low noise, and low-frequency vibration. To some extent, the hybrid induction motor can be regarded as a low-speed synchronous motor. A four-phase motor can operate in four-phase mode or two-phase mode (bipolar voltage drive is required), whereas reactive motors cannot do so. For example, four-phase, eight-step operation (A-AB-B-BC-C-CD-D-DA-A) can fully adopt the two-phase eight-beat operation mode. It is not difficult to find that the conditions are C=, D=. The internal winding of a two-phase motor is completely consistent with that of a four-phase motor. Low-power motors are generally directly connected as two-phase, while higher-power motors often have eight external leads (four-phase) for flexible use and to dynamically change motor characteristics. In this way, they can be used as four-phase motors, or as two-phase motors with windings connected in series or parallel.

CT INGRANAGGI motor classification

Motors are classified by the supply method of excitation current. Permanent magnet synchronous motors are synchronous motors that use permanent magnets to establish the excitation magnetic field; the stator generates a rotating magnetic field, and the rotor is made of permanent magnet material. Synchronous motors require a DC magnetic field for energy conversion, and the DC current producing this field is called the motor's excitation current. Separately excited motors: motors that obtain excitation current from another power source. Self-excited motors: motors that obtain excitation current from the motor itself. Classified by supply frequency, permanent magnet brushless motors include permanent magnet brushless DC motors and permanent magnet brushless AC motors; both require variable frequency power supply when operating as motors. The former requires only a square-wave inverter supply, while the latter requires a sine-wave inverter supply. Classified by air-gap magnetic field distribution: Sine-wave permanent magnet synchronous motor: The magnetic poles use permanent magnet material, and when three-phase sine-wave current is input, the air-gap magnetic field distributes according to a sine law, abbreviated as permanent magnet synchronous motor. Trapezoidal-wave permanent magnet synchronous motor: The magnetic poles are still permanent magnet material, but when square-wave current is input, the air-gap magnetic field distributes in a trapezoidal wave pattern, with performance closer to that of a DC motor. A self-controlled variable-frequency synchronous motor constructed with a trapezoidal-wave permanent magnet synchronous motor is also known as a brushless DC motor.

CT INGRANAGGI motor performance

Motor performance is closely related to its excitation method. Typically, there are 4 types of DC motor excitation methods: DC separately excited motor, DC shunt excited motor, DC series excited motor, and DC compound excited motor. Understand the characteristics of each of the 4 methods: 1. DC separately excited motor: The excitation winding has no electrical connection with the armature, and the excitation circuit is supplied by a separate DC power source. Therefore, the excitation current is not affected by the armature terminal voltage or armature current. 2. DC shunt excited motor: The circuit is parallel, with current division; the voltage across the shunt winding is the same as the voltage across the armature. However, the excitation winding is wound with fine wire and has many turns, resulting in high resistance, which keeps the excitation current low. 3. DC series excited motor: The current is in series, with voltage division; the excitation winding is in series with the armature, so the internal magnetic field of this motor changes significantly with changes in armature current. To prevent large losses and voltage drops in the excitation winding, its resistance should be as low as possible. Therefore, DC series excited motors are usually wound with thicker wire and have fewer turns. 4. DC compound excited motor: The motor's magnetic flux is generated by the excitation currents in two windings.
