    High Performance

    Performance in a Small Package

    Jayashree servo motors deliver great performance due to their compact size and characteristics of high peak torque, high continuous torque and high rated speed— with a low cogging torque.

    • High peak torque is achieved by using sintered Neodymium-Iron-Boron permanent magnets—not plastic-bonded Neodymium—and by optimizing all design parameters.
    • High continuous torque requires a motor that can manage heat. Tightly filled stator windings are designed to avoid build up of hot spots in the motor. The thermal design ensures even and easy heat dissipation. The Class-H (180ºC-rated) winding insulation protects the motor during long operating cycles, and there is no significant deterioration of the magnetic properties of its sintered rare earth magnets.
    • Jayashree servo motors show a flat torque curve over a wide range of speeds.

    Smooth Performance

    Many brushless motors have the problem of a high cogging or detent torque (Detent torque is the amount of torque that must be applied to a motor to overcome the static (magnetic) equilibrium of the motor when it is in an unpowered state of rest).  They also often have significant distortion in their back-EMF signature which leads to high torque ripple.

    • Jayashree brushless servo motors are designed for smooth operation with a low cogging / detent torque and a linear, low-ripple torque output.
    • Each rotor is individually balanced for a smooth performance at all speeds.
    • High quality sealed ball bearings complement the other design features to make a high performing motor.
