RH Series radiation-hardened brushless servomotors accommodate rapid acceleration and deceleration, and offer reliable operation in radiation-intensive applications.
Empire Magnetics introduces RH Series radiation-hardened brushless servomotors.
These motors are designed to accommodate rapid acceleration and deceleration, and reliable operation, in radiation-intensive applications such as fuel processing, nuclear waste storage, processing decommissioned weapons for disposal, and pebble reactors, among others.
High energy, gamma radiation particles will attack nonmetallic materials in a motor, and lubricants, varnish, lamination bonding, and cable insulation will all deteriorate over time and finally crumble.
These motors are constructed with the best available radiation-resistant materials to assure the longest possible service life in a radiation environment.
RH series servomotors are available in four standard frame sizes, with custom sizes available on request.
Across standard frame sizes, these motors are available with continuous output torque ranging from 1.7 to 46Nm or momentary peak torque from 3.4 to 113Nm.
They are available with rotor inertia from 3 to 671kg-mm2, and continuous output power of 700 to 7800W.
RH series brushless servomotors are rated for a total accumulated dose of 200Mrads as standard, with ratings to 1Grads available on a custom basis.
Additional custom radiation-hardened solutions are available including AC induction motors, assemblies and complete RH motion control systems.
