Euro Motors motors are devices that place the rotor in a rotating magnetic field, where it obtains torque under the action of the field, causing the rotor to turn. The rotor is a rotatable conductor, typically squirrel-cage in shape. Invented by electrical engineer Nikola Tesla in 1887. The rotor is a rotatable conductor, typically squirrel-cage in shape. The stator is the non-rotating part of the motor, with the main task of generating a rotating magnetic field. The rotating magnetic field is not achieved by mechanical means. Instead, alternating current is applied to several pairs of electromagnets, causing their magnetic pole properties to cycle, thus equivalent to a rotating magnetic field. Unlike DC motors, these motors do not have brushes or slip rings. Depending on the type of AC power used, there are single-phase and three-phase motors; single-phase motors are used in applications such as washing machines and electric fans, while three-phase motors serve as power equipment in factories.

Euro Motors motor phase angle and torque

The motor phase difference angle (torque angle) is the phase difference δ between the no-load induced electromotive force generated by the magnetic field and the armature voltage. The torque of a synchronous motor is proportional to sin (δ) and reaches the theoretical xxx torque at δ = 90 degrees (for cylindrical motors; it differs for salient-pole motors). Furthermore, since the motor rotates synchronously with the frequency of the armature voltage, the output is proportional to the torque. If the load torque is too high, the motor stops due to "out-of-sync (pull-out)". The torque at this point is called "pull-out torque," and it serves as the phase difference angle within the range of 50-70 degrees.

Euro Motors motor common questions

Motor issues: 2. After the speed-regulated motor accelerates, the speed gradually drops until it stops. In this situation, observe the changes in the ammeter pointer in the speed-regulated motor's electrical cabinet. If the indicated current increases sharply, overload protection devices such as the thermal relay of the main motor will inevitably activate, disconnecting the three-phase power supply to the main motor and stopping operation. At this time, carefully check whether the wiring connections of relevant components in the main motor circuit, the AC contactor of the main motor, and all overload protection devices such as thermal relays in the speed-regulated motor's electrical cabinet are loose or have poor contact causing heating. If these areas have issues, the current will rapidly increase due to poor contact between wires and components in the circuit after the main motor accelerates, causing protective shutdown. When the speed-regulated motor runs at lower speeds, the working current of the main motor is small, so gradual speed drop and shutdown do not occur. However, when the speed-regulated motor accelerates, the high electrical load reveals faults in electrical components. In practical work, it is sometimes observed that terminal blocks in the speed-regulated motor's electrical cabinet heat up due to poor wire contact, even forming oxide layers at the connections, and the wire insulation burns and discolors. These issues seriously affect the normal operation of the main drive motor. Operators must immediately take corresponding measures, such as cleaning the contact surfaces of terminal blocks and wires, tightening wiring screws, removing burnt oxide layers from wires, and replacing severely damaged terminal blocks. 1. The main drive motor produces significant noise during operation. To adjust the dynamic balance of the slip motor, balancing weights are installed at both ends of its armature and magnetic pole rotor. If these devices become slightly loose, the slip motor will deviate from its original position during high-speed rotation. If the fault occurs on the outer surface of the main drive motor, it causes local friction between the armature and the magnetic pole rotor, increasing noise. At this time, shutdown for repair is required to restore the dynamic balance of the armature and magnetic pole rotor, re-establish the original balance weight positions, and secure them to ensure normal operation of the main drive motor.

Euro Motors motor speed measurement methods

A motor converts pulse signals into angular or linear displacement. First, it has good overload capacity. Its speed is not affected by load size; unlike ordinary motors, which slow down when the load increases, stepper motors have strict requirements for speed and position during use. Second, control is convenient. Stepper motors rotate in "steps," making their digital characteristics distinct. Third, the overall structure is simple. Traditional mechanical speed and position control structures are complex and difficult to adjust; using stepper motors simplifies and compacts the overall structure. A tachometer generator converts rotational speed into voltage and transmits it to the input end as a feedback signal. A tachometer generator is an auxiliary motor; installed at the tail end of a standard DC motor, it feeds voltage back to the DC power supply via the tachometer generator to control the DC motor speed.
