Electric motor variable speed drives.

Automatic energy savings help reduce motor loss and electric power costs. Alternating current electric motor speeds can be changed by the use of a frequency converter. Electric gear motor walfront ac 220v 90w single phase asynchronous gear motor high torque deceleration adjustable speed 5k 10k 20k 50k 100k rpm optional 50k 2 3 out of 5 stars 4 178 09 178. Frenic mega drives can provide compact yet powerful solutions for ac drive requirements in both variable and constant torque applications.

With more than 50 years of experience in variable speed drive business driveswarehouse stocks a large selection of ac drives dc drives variable frequency drives vfd variable speed drives adjustable speed drives adjustable frequency drives combo ac motor and drive combination and dc motor and drive combination in a wide range of. A variable speed drive is a device used in electromechanical drives to control the speed and torque of an ac motor by adjusting the motor s input frequency and voltage. Online store of polyspede electronics corporation. Variable speed drives may be either electric hydraulic mechanical or even electronic.

In electric motors used in variable frequency drives various excitation forces exist due to the presence of mechanical and electromagnetic forces. There are three major vfd designs commonly used today. These drives offer a motor current up to 720 a for synchronous or induction motors. This then changes the rotating speed of the motor s internal magnetic field.

A compact variable speed drive can help run fans blowers conveyors and machine tools in areas with limited space. 1 16 of over 3 000 results for variable speed electric motor 60ktyz synchronous gear motor 30rpm dual bearing ac motor cw ccw control 115v 60hz 10w 3 7 out of 5 stars 20. While all variable frequency drives vfds control the speed of an ac induction motor by varying the motor s supplied voltage and frequency of power they all do not use the same designs in doing so. X 6in 1 2hp 115 230 volt single phase model hvbs 56v.

Pulse width modulation pwm current source inverter csi and voltage source inverter vsi. These easy to use drives are well suited for variable torque applications like simple standalone centrifugal fans and pumps. Electric motor variable speed drives operation. This device changes the frequency of the alternating current to the motor.
