EMOD motor Germany EMOD model EMOD price

EMOD motor refers to a low-power single-phase asynchronous motor powered by a single-phase AC power supply (AC220V). This type of motor typically has two-phase windings on the stator, and the rotor is of the 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.

EMOD motor performance

The motor is also known as a motor rotating at synchronous speed. The rotor is attracted and rotated by the surrounding rotating magnetic field generated by the applied AC current. It rotates synchronously with the speed difference between the rotating magnetic field generated by the AC current and the magnetic field generated by the armature current. Open-loop speed control is possible. Without other measures, it cannot start rotating at startup. Induction motors in permanent magnet synchronous motors are more efficient. If the frequency of the electric power applied at startup is high, the stopped rotor will not be able to follow and cannot rotate on its own. Therefore, if the drive power source is not frequency-controlled, a separate starting motor can be provided, or other types of motors can be used. It has a built-in mechanism. Semiconductors have high controllability via inverters, used together with the control circuit.

EMOD motor braking methods

Motor electrical braking methods include: dynamic braking, plugging braking, and regenerative braking. (1) During dynamic braking, the three-phase AC power supply to the motor is cut off, and DC current is fed into the stator windings. 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 braking is divided into load plugging braking and power source plugging braking. Load plugging braking is also known as load hoisting plugging braking. This torque causes heavy loads to descend slowly at a stable speed. The characteristics of this braking are: the power source does not need to be reversed, no specialized 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 source plugging braking: When the motor needs to be braked, simply swap any two phase power lines to reverse the rotating magnetic field, achieving rapid braking. When the motor speed reaches zero, the power is immediately cut off. The characteristics of this braking 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 heavy loads (when a crane motor lowers a heavy load), where the motor speed exceeds the synchronous speed of the rotating magnetic field. At this time, induced current is generated in the rotor conductors, producing a torque in the opposite direction of rotation under the influence of the rotating magnetic field. However, since the motor speed is high, a variable speed device is required for deceleration.
