A driving apparatus and a method for a motor of a treadmill are provided to secure stable driving of a treadmill by switching connection when a load of a treadmill is lowest. A driving apparatus and a method for a motor a converter(220), an inverter(230), a connection portion(240), speed detector(270), a load sensor(260), and a controller(250). The connection portion has Y-connection(249a,249b,249c) and delta-wiring(247a,247b,247c), and the speed detector detects the speed of the treadmill. The load sensor senses the load of the treadmill, and if speed sensed by the speed detector is unsuitable, a switching signal is supplied to the connection portion to switch the connection with another connection. |
