COLZANI INGRANAGGI motor Germany COLZANI INGRANAGGI model COLZANI INGRANAGGI price

COLZANI INGRANAGGI motors are named for their armature winding and field winding connected in series. Single-phase series-wound motors are AC/DC universal motors; they can operate on either AC or DC power supplies. The single-phase series-wound motor is widely used. Its advantages include high speed, high starting torque, compact size, light weight, resistance to stalling, and a wide applicable voltage range. Speed control via voltage adjustment is simple and easy to implement.

COLZANI INGRANAGGI motor speed control

The motor is essentially a servo motor, composed of a synchronous motor and a drive, making it a variable-frequency speed-control motor. The voltage-controlled brushless DC motor is a true brushless DC motor, consisting of a stator and a rotor. The stator comprises an iron core with windings arranged in a forward-reverse-forward-reverse pattern, thereby generating a fixed magnetic field of the N-S group. The rotor consists of a cylindrical magnet (with a central shaft) or an electromagnet with collector rings. This brushless DC motor can produce torque but cannot control direction. In any case, this motor represents a highly significant invention. When used as a DC generator, this invention can produce DC current with continuous amplitude, thus avoiding the use of filter capacitors. The rotor may be permanent magnet, brushed excitation, or brushless excitation. When used as a large motor, self-inductance occurs, requiring protective devices.

COLZANI INGRANAGGI motor installation

Before installing the motor, measure the insulation resistance between the stator winding and the housing, as well as between the main winding and the auxiliary winding. The resistance at ambient temperature must not be lower than 10M Ω; otherwise, dry the windings, for example, using the lamp heating method. The motor shaft extension diameter is ground to standard tolerance dimensions at the factory. Therefore, users must select pulleys or other mating parts with inner diameters conforming to national standard accessories. During installation, push in by hand or gently tap the shaft extension platform. Do not strike heavily with a hammer, as this may vibrate and break the centrifugal switch, preventing motor startup, damaging bearings, and increasing operating noise. Before mounting the motor to the associated machinery, carefully inspect the motor feet for cracks or issues affecting mechanical strength. If any problems are found, do not install or use. Mount the motor on a flat plate with fixing holes and secure it with bolts matching the foot holes. For safety, before operating the motor, connect the grounding wire to the motor's grounding screw and ensure reliable grounding. Use copper wire with a cross-sectional area of no less than 1m m² for the grounding line. Use a time relay to replace the centrifugal switch. The centrifugal switch used in single-phase asynchronous motors is a mechanical switch. When the motor speed reaches more than 70% of the rated speed, the contacts open to disconnect the auxiliary winding (starting winding) or the starting capacitor. If the centrifugal switch is damaged or if low rural voltage frequently burns out the starting capacitor, replace the centrifugal switch with a delay relay (220V type). Connect the two wires from the internal centrifugal switch together, and insert the normally closed contact of the delay relay in series externally. To enhance contact durability, connect multiple contact groups in parallel or add an intermediate relay. Power the time relay coil in parallel with the main winding, and set the action time to 2~6s. Practical experience shows excellent results, avoiding starting capacitor burnout even under low rural voltage conditions, resulting in high user satisfaction.

COLZANI INGRANAGGI motor control methods

Constant V/f control method for motors: The constant voltage-to-frequency ratio control method for permanent magnet synchronous motors is similar to that for AC induction motors. It controls the amplitude and frequency of the motor input voltage to change simultaneously, thereby keeping the motor flux constant. The constant V/f control method can meet the requirements of wide-range speed regulation systems. Without feeding back physical signals such as current, voltage, or position, it can still achieve a certain level of control accuracy, which is the greatest advantage of the constant V/f control method. The constant V/f control method features simple control algorithms and low hardware costs, and has been widely used in the field of general-purpose variable frequency drives. The disadvantages of the constant V/f control method are also obvious. Since there is no feedback of speed, position, or any other signals during the control process, it is almost impossible to obtain information on the motor's operating status, let alone precisely control the rotational speed or electromagnetic torque. The system performance is average, and the dynamic response is poor, especially when the target speed changes or the load undergoes sudden changes, where problems such as step-out and oscillation are prone to occur. Obviously, this control method cannot separately control torque and excitation current, and large excitation currents tend to exist during the control process, affecting motor efficiency. Therefore, this control method is commonly used in general-purpose variable frequency drives with lower performance requirements, such as air conditioners, conveyor belt drive control in production lines, and energy-saving operation of water pumps and fans.
