The characteristics of such design are:
1）The rotor is cageless;
2）The resulting SR motor is brushless and magnet-free; 3）Only the rotor design changes in relation to an IEC standard motor and therefore it can be derived from standard Induction Machines, simply by removing rotor bars and introducing saliency to the rotor.
The inherent advantages of HMSRM motor technology are: 1. Rotor synchronicity, granting a more accurate speed control (no rotor slip); 2. Cage-less rotor means no rotor conductors for:
a. Increased robustness; b. Lower maintenance/cost; c. Thermal improvements; 3. Higher efficiency, up to 94%; 4. Higher torque density; 5. Lower rotor inertia means faster torque dynamics.
Advantages:
HMSRM series motors are characterized by high efficiency, large starting torque, wide speed range, and low noise and vibration. The motor contains no permanent magnetic material, and there is no risk of demagnetization, which is stable and reliable. It can be used to drive a variety of general mechanical equipment, such as fans, water pumps, compressors, etc., to meet the needs of equipment transmission in various industrial automation fields such as machine tools, petroleum, chemical, paper, textile, and so on. The frame of HMSRM series motors adopts the same casing as standard small and medium-sized asynchronous motors, which can realize seamless replacement with traditional low-efficiency asynchronous motors.
