EC Motion motor, German EC Motion model, EC Motion price

EC Motion motors are machines used to convert mechanical energy and AC electrical energy into each other. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have a simple structure, are easy to manufacture, are relatively robust, and can be easily made into high-speed, high-voltage, high-current, and high-capacity motors because they lack commutators (see commutation in DC motors). The power coverage of AC motors is very wide, ranging from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 80s of the 20th century, the largest steam turbine generator had reached 150 ten thousand kilowatts.

EC Motion motor performance

The design of the motor spindle shaft end is also an issue that cannot be ignored for high-speed electric spindles. The selection of electric spindle bearings and their preload technology: bearings used in high-speed spindle units mainly include angular contact ball bearings, magnetic levitation bearings, water-based hydrostatic/hydrodynamic bearings, and air hydrostatic/hydrodynamic bearings. Due to their high cost, complex control systems, and difficult-to-solve heating issues, magnetic levitation bearings are not yet widely applied in high-speed spindle units. Water-based hydrostatic bearings are a popular research topic in China; they utilize the high heat capacity of water and the low temperature rise of the bearing to partially solve the severe heating problem of ordinary hydrodynamic/hydrostatic bearings, and are mainly used in low-speed, heavy-load applications. Air hydrostatic/hydrodynamic bearings have low radial stiffness and impact, but offer good high-speed performance, and are generally used in ultra-high-speed, light-load, precision spindles. Angular contact ball bearings with a dn value are applied in the following high-speed spindle units; they meet requirements well in terms of speed limit, load capacity, stiffness, and precision, are standardized, and are low-cost. The performance of angular contact ball bearings can also be improved by the following methods.

EC Motion motor protection

Motor differential protection includes differential instantaneous trip protection and composite ratio differential protection with or without second harmonic braking. It is suitable for applications with three-side differential current input (three-winding transformers). It features complete and powerful acquisition functions for primary equipment voltage and current analog quantities and switch quantities. It is equipped with standard RS485 and industrial CAN communication ports, and achieves protection and measurement/control functions such as three-winding main transformer differential protection, two-winding main transformer differential protection, two-winding distribution transformer differential protection, generator differential protection, motor differential protection, and non-electrical quantity protection through reasonable configuration.

EC Motion motor performance

Although the working principle of the motor is similar to that of split-phase single-phase asynchronous motors, the former has a much larger rotor resistance than the latter. Therefore, servo motors have three significant characteristics compared to single-unit asynchronous motors: 1, large starting torque. Due to the large rotor resistance, there is a clear difference compared to the torque characteristic curve of ordinary asynchronous motors. It allows the critical slip ratio S0 > 1, which not only makes the torque characteristic (mechanical characteristic) closer to linear but also provides a larger starting torque. Therefore, as soon as there is a control voltage on the stator, the rotor rotates immediately, exhibiting fast starting and high sensitivity. 2, wide operating range. 3, no self-rotation phenomenon. For a normally operating servo motor, as soon as the control voltage is lost, the motor stops running immediately. When the servo motor loses control voltage, it operates in a single-phase state. Due to the large rotor resistance, the two torque characteristics produced by the interaction of the two rotating magnetic fields rotating in opposite directions in the stator with the rotor (T1－S1, T2－S2 curves) and the combined torque characteristic (T－S curve). The output power of AC servo motors is generally 0.1-100W. When the power frequency is 50Hz, voltages include 36V, 110V, 220, 380V; when the power frequency is 400Hz, voltages include 20V, 26V, 36V, 115V, and others. AC servo motors run smoothly and with low noise. However, the control characteristic is nonlinear, and due to the large rotor resistance, losses are high and efficiency is low. Therefore, compared to DC servo motors of the same capacity, they are larger in volume and heavier in weight, so they are only suitable for small-power control systems of 0.5-100W.
