QSH6018 Manual (V1.03 / 06-February-2008) 6 4 Torque figures The torque figures detail motor torque characteristics for full step operation in order to allow simple comparison. For half step operation there are always a number of resonance points (with less torque) which are not depicted. These will be minimized by microstep operation in most applications. 4.1 Motor QSH6018-45-28-110 Testing conditions: 30V supply voltage; 3.0A RMS phase current Figure 4.1: QSH6018-45-28-110 Speed vs.

QSH6018 Manual (V1.03 / 06-February-2008) 8 5 Considerations for Operation The following chapters try to help you to correctly set the key operation parameters in order to get a stable system. 5.1 Choosing the best fitting Motor for an Application For an optimum solution it is important to fit the motor to the application and to choose the best mode of operation. The key parameters are desired motor torque and velocity.
QSH6018 Manual (V1.03 / 06-February-2008) 5.2 9 Motor Current Setting Basically, the motor torque is proportional to the motor current, as long as the current stays at a reasonable level. At the same time, the power consumption of the motor (and driver) is proportional to the square of the motor current. Optimally, the motor should be chosen to bring the required performance at the rated motor current.
QSH6018 Manual (V1.03 / 06-February-2008) 5.3 10 Motor Driver Supply Voltage The driver supply voltage in many applications can not be chosen freely, because other components have a fixed supply voltage of e.g. 24V DC. If you have to possibility to choose the driver supply voltage, please refer to the driver data sheet, and consider that a higher voltage means a higher torque at higher velocity. The motor torque diagrams are measured for a given supply voltage.
QSH6018 Manual (V1.03 / 06-February-2008) 5.4 11 Back EMF (BEMF) Within SI units, the numeric value of the BEMF constant has the same numeric value as the numeric value of the torque constant. For example, a motor with a torque constant of 1 Nm/A would have a BEMF constant of 1V/rad/s. Turning such a motor with 1 rps (1 rps = 1 revolution per second = 6.28 rad/s) generates a BEMF voltage of 6.28V.
QSH6018 Manual (V1.03 / 06-February-2008) 12 5.5.1 Fullstepping When operating the motor in fullstep, resonances may occur. The resonance frequencies depend on the motor load. When the motor gets into a resonance area, it even might not turn any more! Thus you should avoid resonance frequencies. Hints: Q: How to avoid motor resonance in fullstep operation? A1: Do not operate the motor at resonance velocities for extended periods of time.
