A: Usually we quote within 8 hours after we get your inquiry. Q: What’s your MOQ? A: It will be no MOQ, If we have the products in stock. We will discuss the MOQ according to customer’s exact situation. Q: How long is your delivery time? A: The general delivery time is 15-20 days after receiving your order confirmation. Anther, It will only take 1-2 days if we have stock.A DC motor's speed and torque characteristics vary according to three different magnetization sources, separately excited field, self-excited field or permanent-field, which are used selectively to control the motor over the mechanical load's range. Self-excited field motors can be series, shunt, or a compound wound connected to the armature. A permanent magnet DC motor is characterized by a linear relationship between stall torque when the torque is maximum with the shaft at standstill and no-load speed with no applied shaft torque and maximum output speed. There is a quadratic power relationship between these two speed-axis points.
