What causes motor to stall in slow speeds?

A motor can stall at slow speeds due to several factors, including excessive load that exceeds its torque capacity, inadequate voltage supply, or mechanical issues such as friction or binding in the system. Insufficient cooling can also lead to thermal overload, causing the motor to stall. Additionally, poor control settings or malfunctioning speed controllers may prevent the motor from maintaining the necessary speed, leading to a stall condition.
