Product overview - Electrocraft - #3

Synchronous motors run at an exact speed. The speed will not vary with load or volt­age. We make hysteresis and reluctance types in a wide range of frame sizes. EAD hysteresis-synchronous motors develop smooth, constant starting and accelerating torques. They synchronize any load within their torque rating—regardless of inertia.

EAD reluctance-synchronous motors function at constant speeds—and cost very little more than standard induction motors.

In single and 3-phase models, EAD induc­tion motors are designed for a wide range of commercial and military applications. For low starting torque applications, per­manent-split capacitor types offer higher efficiency and a higher power factor than other designs. Capacitor start and split phase motors are used when a high start­ing torque is required. EADmotors manu­factures both high and low slip permanent split capacitor motors to meet a wide range of application requirements.

EADmotors provides frameless versions of all of our designs. Stator/rotor sets offer the advantage of eliminating component parts in a system such as redundant bear­ings and couplings. They also allow sys­tems to be smaller and more reliable as possible failure modes are eliminated at the design stage. Contact us for more in­formation about how stator/rotor sets can make your products more competitive.

In addition to brushless DC motors, EADmotors manufactures a wide range of other types of motors and controls as well as blowers and fans.

Torque motors are com­monly used where prolonged stalled operation or special running-torque characteris­tics are required. They may involve either static or dy­namic forces.

Applications may require smooth, moderate accelerat­ing torque and low speed with speed ranges from near synchronous to zero.
