At constant operating voltage, speed decrease is proportional to load increase. Matching motors to meet desired operating characteristics is possible with the wide range of different motor coil windings available. Alternatively, using a gearhead or gearmotor to reduce output speeds is the preferred solution over running a motor at low speeds. Driving motors into hard stops will also reduce motor lifetime. Environmental Influences Temperature, humidity, vibration, operating point, torque load, and type of installation all affect motor applications and life.
Heat is generated in the motor windings.
This heat needs to be carried away through the motor's casing. Measures such as good air circulation and heat sinking can significantly lower motor temperatures. The maximum rotor temperatures shown on MicroMo data sheets may not be exceeded, even for a short period of time. The motor's ability to perform is directly related to the difference between ambient temperature and maximum permissible rotor temperature. Winding resistance rises and magnetic forces decrease as temperature rises.
