According to the company, its Synchron timing motors are the industry leader in applications requiring spring return capability. The motor can be stalled indefinitely in speeds of 1 rpm and faster without electrical or mechanical damage to the motor. This stalling capability, coupled with consistent reset torques, reportedly make the motor ideally suited for motorized valve and damper applications.
Synchron motors are custom-built using a wide variety of output shaft configurations, mounting styles, speeds, voltages, and frequencies. Hansen's complete motor product line includes stepper, brush d.c., hysteresis synchronous, and permanent magnet synchronous.
