Brushless Motors

Empire Magnetic's family of dustproof rated motor/resolvers bundled with a drive system are ideal for efficient closed loop motion control applications. Empire Magnetic's brushless motor with a resolver form a single rugged component suitable for hostile enviromnents. Drive electronics can be removed and controlled from a more hospitable location via RS-232.

Motor Features:

These motors can accomodate rapid acceleration and deceleration. The brushless construction is made for reliability. The brushless resolver can be used as the feedback device. There is high torque to inertial ratio and stall torques from 14 to 451 lb-ins. The unique structure allows maximum power ratings, anti cog design and long life bearings.

Frame size selection:

The 3.25 inch square frame brushless motors (R30 series) include motors with continuous output torque ranging from 15 to 30 inch lb. (1.7-3.4 Nm), or momentary peak torque from 30 to 70 inch lb. (3.4 - 7.9 Nm). Rotor inertia from .17 to .31 oz-in². Continuous output power of 700 to 975 watts.

The 4.25 inch square frame brushless motors (R40 series) include motors with continuous output torque ranging from 35 to 60 inch lb. (3 - 6.8 Nm), or momentary peak torque from 70 to 14 inch lb. (7.9 - 15.8 Nm). Rotor inertia from .39 to 1.3 oz-in². Continuous output power of 900 to 1500 watts.

The 5.75 inch square frame brushless motors (R60 series) include motors with continuous output torque ranging from 75 to 150 inch lb. (8.4-16.9 Nm), or momentary peak torque from 150 to 350 inch lb. (16 - 39 Nm). Rotor inertia from 2.6 to 5.79 oz-in². Continuous output power of 2600 to 3400 watts.

The 7.5 inch square frame brushless motors (R80 series) include motor with continuous output torque ranging from 160 to 400 inch lb. (18 - 46 Nm), or momentary peak torque from 400 to 1000 inch lb. (45 - 113 Nm). Rotor inertia from 15 to 36.7 oz-in². Continuous output power of 5900 to 7800 watts.

Note: Power output is dependent upon cooling capacity of mounting or system.
