Motion control technology for stepper motors

Motion Control Products has introduced Accustep motion control technology from IMS.

When applied to stepper motors, the technology prevents the loss of synchronisation due to transient or continued overload, extreme acceleration or deceleration or excessive slew speed.

As a result of this, Accustep allows the safe operation of a motor at its maximum torque curve, according to the company.

Therefore, sizing a motor with a 25-50 per cent torque margin is no longer required.

This may also allow a smaller frame size or a shorter stack length motor in some applications.

Accustep also enables a system to ride through known transient overloads, further eliminating the requirement for a larger motor.

By enabling variable current control, motor heating and energy consumption can be reduced.

There are two MDrive Accustep product versions available in the size of Nema23 and Nema34.

One is Step Torque Speed, where Accustep is integrated with a stepper motor, a microstepping drive and an internal encoder, featuring three Accustep operating modes: Step, Torque and Speed.

The other version is Motion Control, where Accustep is integrated with a fully programmable motion controller, a stepper motor, a microstepping drive and an internal encoder.

MDrive Accustep systems offer clear advantages in a low-cost package as an alternative where brushless technology is required for a range of motion control applications such as point-to-point positioning, conveyor control, webb handling, drilling and low-end camming.

With the addition of torque control, rotary and linear positioning to torque specifications is also now possible.
