力矩电机如何控制？ 点击：9272 | 回复：41
如果提供的是JYJ力矩电机,三根线入的,则只有一种控制器,一般是不用力矩电机来调速的,只有在收卷行业,如电缆,纸张,线材,纺材等行业才用力矩电机,
其原理是设定张力力矩,来多少收多少,不来则赌转.
跟速度实际上是没有太多联系的.

The Direct Drive DC torque motor is a servo actuator which can be directly attached
to the load it drives. It has a permanent magnet (PM) field and a wound armature
which act together to convert electrical power to torque. This torque can then be
utilized in positioning or speed control systems. In general, torque motors are
deigned for three different types of operation:
• High stall torque (“stand-still” operation) for positioning systems
• High torque at low speeds for speed control systems, and
• Optimum torque at high speed for positioning, rate, or tensioning systems.
Direct drive torque motors are particularly suited for servo system applications
where it is desirable to minimize size, weight, power and response time, and to
maximize rate and position accuracies.
Torque Motor or Servo Motor?
A torque motor is typically described as having a “pancake”
configuration, i.e., a large diameter and a narrow width. This
configuration generally has a large number of poles to
increase the torque available in a given volume. This large
number of poles, however, also causes more commutation arcing
as speed increases than for a motor with few poles. Torque
motors are most commonly used in positioning and slowspeed
rate applications where commutation is not a limitation.
A servo motor is characterized by a long, small diameter
configuration. Lengthening a motor while maintaining a
small diameter allows a significant increase in torque while
minimizing the increase in rotor inertia. The end result is an
improved mechanical time constant and, therefore,
improved motor response. Servo motors are most commonly
used in running applications where good high-speed commutation
is demanded and operation at or near stall is not
required.
