In this paper, a deep slot universal motor is designed for electric power tools. The deep slot structure can reduce the cost of universal motor materials and improve production efficiency.
Optimal design of stator and rotor slot of induction motor for electric ...
Slotless motors are designed to optimize smoothness and create predictable torque output with minimal non-linear effects. Commonly referred to as slotless motors when rotary and air core motors when linear, slotless motor designs place only copper phase coils in the air gap of the motor.

The motor cogging torque of the pear-shaped round slot was the smallest, with a value of 460 mN·m, and the motor reluctance torque of the pear-shaped trapezoidal slot was the smallest, with...
Comparing Slotted vs Slotless Brushless DC Motors - Haydon Kerk Pittman
The average torque of the 8/48 pole/slot motor is increased from 13.66N·m to 13.97N·m, and the torque ripple is reduced from 24 to 12.9%. The average torque of the traditional structure and the hybrid pole structure of the 8/12 pole/slot motor is 12.1N·m, and the torque ripple is reduced from 35.5 to 14.1% (Fig. 9 ).
