FAQ What type of servo drive is compatible with this DY71S/TH motor?This is a permanent magnet synchronous motor, which requires a specific servo drive capable of controlling such motors. It would typically be paired with an SEW-Eurodrive Movidrive or similar series inverter that supports synchronous motor control and can handle the 400V/225Hz specification. What is the significance of the 225 Hz nominal frequency?The high nominal frequency of 225 Hz is directly related to its high nominal speed of 4500 rpm. This indicates the motor is designed for high-speed applications and must be operated with a variable frequency drive (VFD) that can output this frequency, as standard mains are only 50/60 Hz. Can the mounting position (IM M1) be changed?The mounting position specified as IM M1 (foot-mounted, horizontal shaft) is determined by the gearbox design and lubricant fill level. While some gearboxes support universal mounting, changing from the specified M1 position may require adjusting the oil level or breather plug position. Always consult the manufacturer’s documentation before operating in a different orientation.
