Elmot motor motor German Elmot motor model Elmot motor price

Elmot motor motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It broadly refers to all machines that can convert mechanical energy into electrical energy and electrical energy into mechanical energy. The motor housing protection rating is IP44, and the cooling method is IC0141 totally enclosed fan-cooled (TEFC). The ambient air temperature varies with the seasons but does not exceed 15℃ to 40℃. Altitude does not exceed 1000m. Rated frequency, rated voltage, insulation class, and duty cycle are shown on the nameplate. When the supply voltage varies within ±0.05 of the rated value (frequency at rated value), the motor output power maintains the rated value.

Elmot motor motor advantages

The motor can be installed as a whole on the wheel axle to form an integrated direct drive system, meaning each wheel axle is a drive unit, eliminating the need for a gearbox. Advantages of permanent magnet synchronous motors: high power efficiency and high power factor of the permanent magnet synchronous motor itself; low heat generation, resulting in a simple, compact, and quiet motor cooling system; the system adopts a fully enclosed structure with no transmission gear wear, no transmission gear noise, and is lubricant-free and maintenance-free; permanent magnet synchronous motors allow high overload current, significantly improving reliability; the entire transmission system is lightweight, with lower unsprung weight than traditional wheel axle transmissions and higher power per unit weight; the absence of a gearbox allows flexible bogie system design, such as flexible bogies and single-axle bogies, greatly improving train dynamic performance. Due to the use of permanent magnet poles, especially rare earth permanent magnets (such as NdFeB), which have high magnetic energy product and can achieve high air gap flux density, the motor is smaller and lighter for the same capacity. The rotor has no copper or iron losses, nor friction losses from slip rings and brushes, resulting in high operating efficiency. Low moment of inertia allows high pulse torque, achieving higher acceleration, good dynamic performance, compact structure, and reliable operation.

Elmot motor motor working principle

The motor's DC disc brake is installed on the end cover at the non-shaft extension end of the motor. When the brake motor is connected to the power supply, it operates simultaneously. Due to electromagnetic attraction, the electromagnet attracts the armature and compresses the spring, disengaging the brake disc from the armature end cover, allowing the brake motor to start running. When the power is cut off, the brake motor electromagnet loses its magnetic attraction, and the spring pushes the armature to press against the brake disc. Under the action of friction torque, the brake motor stops immediately. We also produce corresponding YDEJ two-speed (multi-speed, far-pole ratio) motors. The brake motor power is supplied by the rectifier inside the motor junction box. For 3 kW and below, it is AC220V-DC99V; for 4 kW and above, it is AC380V-DC170V (special designs such as DC24V can be made according to factory requirements). The YEJ series electromagnetic brake motor enables rapid braking after power loss. Fast braking time for YEJ2-63-90 motor is less than 0.15 seconds, and for YEJ-100-160 motor is less than 0.20 seconds. The brake motor can achieve slow braking by changing the wiring in the junction box according to user requirements. This series of motors features low noise and reliable braking performance. Its working principle is: when the brake motor is energized, it rectifies 220V AC to obtain 198V DC. At this time, the armature is electromagnetically attracted, placing the brake disc in a rotatable state and allowing the brake motor to rotate freely. When the brake motor loses power, the electromagnet de-energizes, and the armature is immediately pushed by the spring to press the brake disc against the motor rear end cover, stopping rotation.

Elmot motor motor classification

Motors feature simple structure, small size, high efficiency, and high power factor. Permanent magnet synchronous motors have achieved success in medium and low-voltage applications in industries such as metallurgy (ironworks and sintering plants), ceramics (ball mills), rubber (internal mixers), petroleum (pumping units), and textiles (twisting machines, fine spinning machines), gradually accumulating design and operational experience. Classification by permanent magnet structure: Surface-mounted Permanent Magnet Synchronous Motor (SPMSM), Interior Permanent Magnet Synchronous Motor (IPMSM). Classification by stator winding induced EMF waveform: Sinusoidal Permanent Magnet Synchronous Motor, Brushless Permanent Magnet DC Motor. The starting current multiple of permanent magnet synchronous motors is approximately 9 times, which is 10% higher than that of asynchronous motors. Permanent magnet synchronous motors cannot use reduced-voltage starting methods. Under reduced-voltage supply conditions, their asynchronous starting torque drops more significantly than that of asynchronous motors, causing starting difficulties. Regarding the self-starting characteristics of permanent magnet synchronous motors and feedback current during system short circuits, parameters vary significantly among different manufacturers. Due to the difficulty in obtaining relevant data, the application of permanent magnet synchronous motors introduces some uncertainties to the short-circuit level and starting calculation verification of the plant power supply system.
