SIEMENS motor Germany SIEMENS model SIEMENS price

The SIEMENS motor has a set of adjustable eccentric weights installed at each end of the rotor shaft, utilizing the centrifugal force generated by the high-speed rotation of the shaft and eccentric weights to obtain excitation force. Vibration motors have a wide vibration frequency range; only when the excitation force and power are properly matched can mechanical noise be reduced. Vibration motors are classified into six categories, including by starting and operating mode, and by operating speed.

SIEMENS motor braking method

Motor electrical braking methods include dynamic braking, plugging, and regenerative braking. (1) During dynamic braking, the three-phase AC power supply of the motor is cut off, and DC power is fed into the stator winding. At the instant the AC power is cut off, due to inertia, the motor continues to rotate in the original direction. This method is characterized by smooth braking, but requires a DC power source. For high-power motors, the cost of the required DC equipment is high, and the braking force is small at low speeds. (2) Plugging is divided into load plugging and power supply plugging. Load plugging is also known as load reversal plugging. This torque causes heavy loads to descend slowly at a stable speed. The characteristics of this braking method are: the power supply does not need to be reversed, no special braking equipment is required, and the braking speed can be adjusted. However, it is only applicable to wound-rotor motors, where a large resistance must be connected in series in the rotor circuit to make the slip greater than 1. Power supply plugging: When the motor needs to be braked, simply swap any two phase power lines to reverse the rotating magnetic field for rapid braking. When the motor speed reaches zero, the power supply is immediately cut off. The characteristics of this braking method are: fast stopping, strong braking force, and no need for braking equipment. However, during braking, the high current and large impact force can easily cause the motor to overheat or damage components in the transmission part. Regenerative braking, also known as feedback braking, occurs under the action of a heavy load (such as when a crane motor lowers a load), where the motor speed exceeds the synchronous speed of the rotating magnetic field. At this time, an induced current is generated in the rotor conductors, producing a torque in the opposite direction of rotation under the action of the rotating magnetic field. However, since the motor speed is high, a speed-changing device is required for deceleration.

SIEMENS motor working principle

Inside the motor, ring-shaped permanent magnets are fixed. Current passing through the coils on the rotor generates Ampere force. When the coils on the rotor are parallel to the magnetic field, the direction of the magnetic field experienced upon further rotation will change. Therefore, the brushes at the end of the rotor alternately contact the commutator segments, changing the direction of the current in the coils. The direction of the resulting Lorentz force remains unchanged, allowing the motor to maintain rotation in one direction. The working principle of a DC generator is to convert the alternating electromotive force (EMF) induced in the armature coils into direct EMF at the brush terminals, relying on the commutation action of the commutator and brushes. The direction of the induced EMF is determined by the right-hand rule (magnetic field lines point into the palm, the thumb points in the direction of conductor motion, and the other four fingers point in the direction of the induced EMF in the conductor). The direction of the force on the conductor is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature, known as electromagnetic torque in rotating machines. The direction of the torque is counter-clockwise, attempting to rotate the armature counter-clockwise. If this electromagnetic torque can overcome the resisting torque on the armature (such as resisting torque caused by friction and other load torques), the armature will rotate counter-clockwise.

SIEMENS motor applications

A single-phase motor refers to an asynchronous motor powered by 220V AC single-phase power. Because 220V power supply is very convenient and economical, and household electricity is also 220V, single-phase motors are not only widely used in production but are also closely related to people's daily lives. Especially with the continuous improvement of living standards, the use of single-phase motors in household appliances is increasing. Applications in production include micro water pumps, grinding machines, threshers, crushers, woodworking machinery, and medical devices. In daily life, applications include electric fans, hair dryers, exhaust fans, washing machines, and refrigerators. There are many types, but the power is relatively small. This type of motor usually has two-phase windings on the stator, and the rotor is a standard squirrel-cage type. Different distributions of the two-phase windings on the stator and different power supply conditions can produce different starting and operating characteristics.
