The efficiency of a properly designed synchronous motor will usually fall in range
60 to 70%
75 to 80%
85 to 95%
99 to 99.5%
85 to 95%
The efficiency of a properly designed synchronous motor generally falls within the range of 85% to 95%. This efficiency is indicative of how effectively the motor converts electrical energy into mechanical energy without significant losses.

Synchronous motors operate at synchronous speed, meaning the rotor rotates at the same frequency as the supply current. The high efficiency is attributed to the design that minimizes losses due to resistance, core losses, and other operational inefficiencies.
Synchronous motors have a high efficiency due to their operational characteristics.
The efficiency continues to improve with better designs and materials.
High efficiency and performance under various load conditions.
Constant speed operation regardless of load variations.
Require a reactive power source or capacitor for operation.
More complex starting mechanism compared to induction motors.
Used in large industrial applications requiring precise speed control.
Commonly used in synchronous condensers for power factor correction.
Standard synchronous motor efficiency can be influenced by design and load conditions.
Option D is incorrect as achieving 99% or higher efficiency is impractical for conventional synchronous motors.
C is correct тАФ Synchronous motors typically achieve efficiency levels ranging from 85% to 95%.
Understand the impact of load and design on motor efficiency to answer related questions effectively.
