Product: Separately excited synchronous motor Standard Efficiency
The process of making the rotor form a rotating magnetic field according to the principle of electromagnetic induction is called excitation. The excitation motor changes the excitation magnetic field by changing the excitation coil current, and the magnetic field strength is large and controllable. Compared with asynchronous motors and permanent magnet synchronous motors, the torque of the excitation motor can be adjusted within a certain range to enhance output control. And it has the characteristics of high efficiency, low noise, balanced heat conduction, and stable operation. In addition, the current required by the excitation motor is small, the electromagnetic arrangement is more regular, and the service life is longer. ZF always focus on leading the development of E-Drive system in New energy field. Base on the maturing Hair Pin technology, ZF developed a new generation SESM named i²SM which can be the best solution for the high cost, low life and sustainable development. ZF also start a SESM mass-produced in China at the beginning of this year.
1.low installation space required, Inductive exciter within rotor shaft, higher volumetric power density, full fit the layout requirements of different powertrains 2. Lower unit cost under the same peak power 3. High power density: the cycle efficiency of high-speed road conditions is nearly 15% higher than traditional PSM 4. Manufacturing platform Sharing: induction motor and PMSM share the production line 5. Non-touch carbon brush design: abrasion avoid 6. In order to meet the sustainability of materials for new energy vehicles, optimize the raw material selection and structure for E-motors.
ZF has launched the two plants in Shenyang and Hangzhou and the E-mobility global core R&D center located in Songjiang, Shanghai. ZF provides customer with the development and manufacture of various types of E-motors, such as ASM, PSM, and SESM for 400V and 800V model. Except the world's leading Hair Pin technology, ZF still focuses on the new technology development, such as electric excitation, wave winding, oil cooling in slot, near-slot oil cooling, wave winding and product localization. ZF also provides the customer with products of the various performance levels and cost.
ZF believes advanced technology, sustainable development, local R&D and manufacturing will surely become the trend of the E-mobility industry. As the Chinese market becomes increasingly important in the global automotive industry, ZF will still be“in China, for China”, and is willing to work together with partners to meet the opportunities and challenges from the new energy vehicle market.
