4 FAQs about DC motor with power generation instead of inverter

Can a brushed DC motor be used as a generator?

Both brushed and brushless DC motors can be operated as generators. However, there are some important points to consider when designing the drive. Every now and then, I'm asked about the suitability of maxon DC motors for the use as a generator. Since our motors are very efficient, this is also true when operated as generators.

How do I convert a motor into a generator?

When converting a motor into a generator, the first essential modification involves ensuring the motor is compatible with generator operation. This typically requires the use of a DC motor or an AC induction motor with specific characteristics.

How to choose a motor for a generator?

In order to fulfill the torque requirements, you might need a motor with a much higher power rating than the generated power; in particular if the generator speed is rather low compared to typical motor speeds. The amount of torque on the generator defines the size and type of the motor-generator.

What is the difference between a generator and a motor-generator?

The amount of torque on the generator defines the size and type of the motor-generator. As such, users should select a motor type with continuous torque higher than generator torque.
