BLDC motor with high torque density for variable valve timing and lift systems

This 3-phase motor with 6 coils features first rate performance: peak torques of above 1.2 Nm, mechanical power of over 180 W and peak speeds reaching 10,000 rpm. A high resolution position sensor ensures excellent positioning resolution. This electromagnetic structure has been developed and patented by Moving Magnet Technologies (MMT), subsidiary de SONCEBOZ.


This direct drive electric motor is compatible with standard BLDC control mode and can therefore is easily compatible with existing engine control units. It can operate in extreme temperatures [-40 °C ; +150 °C] and is IP67. The extremely tough High Accelerated Lifetime Tests (HALT) used during its development and automatic assembly ensure robustness and long service life. Therefore this 5642 Series BLDC motor is ideal for any automotive application featuring very high vibration and thermal stresses requiring high positioning dynamics in a confined space, such as engine downsizing or transmission applications.
