to induction motors. In modern induction motors, the most common type of rotor has cast-aluminum conductors and short-circuiting end rings. The rotor turns when the moving magnetic field induces a current in the shorted conductors. The speed at which the magnetic field rotates is the synchronous speed of the motor and is determined by the number of poles in the stator and the frequency of the power supply. Synchronous speed is the absolute upper limit of motor speed. At synchronous speed... (read more)Browse AC Motors Datasheets for Sinotech Motors

accuracy for stepper motors is comparable to closed-loop servocontrollers for many applications. Conventional hybrid stepper motors are rarely used in closed-loop systems because torque falls rapidly as current increases above the peak torque point -- putting them outside typical control limits. The stepper motor's torque also decreases as speed rises. If driven too fast, hybrids lose position accuracy by skipping steps. A stepper motor's peak torque is limited by the flux level that saturates... (read more)Browse Stepper Motors Datasheets for Sinotech Motors
