Most stepper motors have class B insulation which is rated at 130 degrees C. Motor case temperatures of 90 degrees C will not cause thermal breakdowns. Motors should be mounted where operators cannot come into contact with the motor case.

Keeping a motorcycle motor at the correct operating temperature is important to the life of the engine. If the motor runs too hot, excessive RPM is what will kill the motor as temperature will soar higher & the oil will loose its lubrication properties. In this situation the edges of the piston crown can start to melt, combined with any carbon deposits glowing; this leads to a pre-ignition situation. See similar questions...

Resonance is an unstable condition when running a step motor. Resonance usually occurs between 2-4 rev/sec and can be alleviated in most situations by putting a load on the motor, changing from full stepping to half or microstepping, or increasing your acceleration through the resonance zone.

A stepper motor controller, more generally called Motion controller, is a system that control the rotation of motors (stepper, brushless, sevomotors) with the purpose of moving a mechanical (axis in CNC machines) to a determined position. Motion controller must not be confused with motors drivers that are the power part of a positioning system. The firsts are those systems based on a PC that give the signals for the motors through the parallel port. See similar questions...

The resolution of an axis system moved by stepper motors depend uniquely by the mechanical. The stepper motors have generally a 1.8? step angle so they make a complete rotation with 200 step when drive at full step. For example, if the motor drive a screw of 4 mm., a complete turn will make a displacement of 4 mm. and so the resolution will be 4/200 mm= 0.02 mm. Obtaining a mechanical with backslash less than this is very difficult. See similar questions...

The moderns stepper motors can reach rotation speed of 1500 RPM. It must be considered that the motor torque curve decrease considerably with the increasing of the step frequency. If we take a screw of 4 mm and we run it at 1500 RPM we obtain a displacement speed of 1500*4mm=6000mm/min or 6 m/min. In practice the stepper motors runs at max 600 RPM because the torque decrease above that values. See similar questions...

I like servo motors because: they are quiet, more power at high rpms, machines can move at least three times faster than steppers, rotational movement is smooth instead of jerky. See similar questions...

AMD and Intel both have maximum temperature ratings for their CPUs listed around 80C. If your CPU gets this hot, you?ve got some serious problems. Most people try and keep the CPU temperature below 40C at idle and below 55C at load. See similar questions...

Servos produce more torque at any speed than comparable stepper motors. This can be up to 400% more torque for equally rated motors. Servos are under closed-loop control via their encoders, allowing additional power to be sent to the motor when resistance is encountered. Steppers, on the other hand, will simply stall and lose their position relative to the control -- resulting in improperly machined parts. See similar questions...

The large sunshade will protect the telescope from heating by direct sunlight, allowing it to cool down to a temperature below 50 kelvin (equal to -370 degree F, or -223 degree C). The near-infrared instruments (NIRCam, NIRSpec, FGS) will work at about 39 K (-389 degree F, -234 degree C) through a passive cooling system. The mid-infrared instrument (MIRI) will work at a temperature of 7 K (-447 degree F, -266 degree C), using a cryocooler system. See similar questions...

For safety reasons, an engineer wants to know how long it takes for a drive's DC Bus to dissipate once the main power is disconnected. In theory, the drive's bus will never dissipate completely due to the logarithmic behavior of the DC Bus capacitor but in actuality we can do the calculations based on a final voltage that approaches zero volts. The minimum amount of time required before the drive dissipates the voltage can be worked out as follows: Motor Resistance (D062M) = Rm = 3. See similar questions...

If you are only operating one stepper motor using any of our boards which have the GenStepper firmware installed, and if that motor does not require use of the Double Current Mode of operation, then you may operate up to 2 relays at the same time as you operate the stepper motor. The manual is in Adobe Acrobat format, and is available from our downloads page here. See similar questions...

All poultry should reach a safe minimum internal temperature of 165 °F. (Sources: Kitchen Thermometers; Use a Food Thermometer) See similar questions...

There are several ways: 1. Adjust the operating current (a margin of torque must be present, since lowering the current decreases the torque). This suppresses heat generation during operation. 2. Use the driver functions. The "All Winding Off" function and "Automatic Current Cutback" function suppress heat generation when the motor is stopped. 3. Install the motor on a plate with good heat conductivity. 4. Install a fan to cool the motor. See similar questions...

The primary purpose of the device is to view remote objects for short periods of time. We will include a power adapter which can be plugged into a wall outlet and will allow the camera to stay on continuously. See similar questions...
