†TORQUE MOTORS  (ROTARY SYNCHRONOUS MOTORS RM-36 series)

torque rotary motors

Torque motors are designed as direct drives. Torque motors are frameless equipment motors. |
Thith motors consist of permanent-magnet rotor and laminated stator.
Ruchservomotor JV designed and produced three series of torque motors: torque motors for instrument-industry (series RM-24, series RSMR-24) and for machine-building industry (series RM-36).
The feature of synchronous motors series RM-24 is small dimensions for low dimensions(profile) position systems.

Motor description:

Torque motor series RM-36 (synchronous rotary motor ) consist of a fixed primary coil unit (stator or primary part) and rotate magnet ring (rotor or secondary part).
The stator is composed of a coil unit that is encapsulated in thermally conductive epoxy.
The rotor consists of steel ring with glued permanent magnets.
The smoothness of movement is achieved by sinusoidal commutation of currents in the coils.

Advantages:

Absence of mechanical transmissions, high precision, repeatability and resolution, no backlash,smooth movement, low profile, hollow shaft.

Applications

machine tools; high torque rotary axis, motors for lift equipment , pick and place machines, indexing tables.

Note:
1. Peak current Ip is create peak torque Mp (2Е3sec).
2. Value of a current from the amplifier at "star" connection of phases is same below, at "triangle" connection of phases is multiplied on 1,73.
3. Air gap between stator and rotor must be maintained according to the specified dimension tolerances..
4. Maximal temperature of rotor 70∞C.
   The stator has built-in thermal sensor threshold type on temp 120 ∞C.
5. Resistance at Star connection =2RPH, at triangle connection = 0.65 RPH
6. Inductance at Star connection =2LPH, at triangle connection = 0.65 LPH
7. [S/T] - values at Star/Triangle connection of phases
8. All data tolerance ±10%.
9. Values are subject to change without previous notice.
10. Maximal supply voltage 600 VDS.
